Why is Venus rotating in the wrong direction? Which planet rotates in the opposite direction Which planet rotates against all planets
Planet Venus interesting facts. Some you may already know, others should be completely new to you. So read on and learn new interesting facts about the "morning star".
Earth and Venus are very similar in size and mass, and they revolve around the Sun in very similar orbits. Its size is only 650 km less than the size of the Earth, and its mass is 81.5% of the Earth's mass.
But that's where the similarities end. The atmosphere is 96.5% carbon dioxide, and the greenhouse effect raises temperatures up to 461 ° C.
2. The planet can be so bright that it casts shadows.
Only the Sun and Moon are brighter than Venus. Its brightness can range from -3.8 to -4.6 magnitudes, but it is always brighter than the brightest stars in the sky.
3. Hostile atmosphere
The mass of the atmosphere is 93 times that of the Earth's atmosphere. The surface pressure is 92 times that of the Earth. It is like diving a kilometer under the surface of the ocean.
4. It rotates in the opposite direction compared to other planets.
Venus rotates very slowly, the day is 243 Earth days. Even stranger is that it rotates in the opposite direction compared to all other planets in the solar system. All planets rotate in a counterclockwise direction. Except for the heroine of our article. It rotates clockwise.
5. Many spacecraft have managed to land on its surface.
In the midst of the space race, the Soviet Union launched the Venus series of spacecraft and some successfully landed on its surface.
Venera 8 was the first spacecraft to land on the surface and transmit photographs to Earth.
6. People are used to thinking that there are "tropics" on the second planet from the Sun.
While we sent the first spacecraft to study Venus from close range, no one really knew what was hidden below the thick clouds of the planet. Science fiction writers dreamed of a lush tropical jungle. The hellish temperature and dense atmosphere surprised everyone.
7. The planet has no satellites.
Venus looks like our twin. Unlike Earth, it has no moons. Mars has satellites, and even Pluto has satellites. But she ... no.
8. The planet has phases.
Although it looks like a very bright star in the sky, if you can look at it with a telescope, you will see something different. When looking at it through a telescope, you can see that the planet goes through phases like the moon. When it is closer, it looks like a thin crescent moon. And at the maximum distance from the Earth, it becomes dim and in the form of a circle.
9. There are very few craters on its surface.
While the surfaces of Mercury, Mars and the Moon are littered with impact craters, there are relatively few craters on the surface of Venus. Planetary scientists believe that its surface is only 500 million years old. Constant volcanic activity smooths out and removes any impact craters.
10. The last ship to explore Venus is the Venus Express.
Is it true that venus spins counterclockwise ??? and got the best answer
Answer from Ulenspiegel [guru]
Yes it's true. And Uranus generally lies "on its side".
Answer from Glukhov Ivan[newbie]
venus rotates in the opposite direction to its orbital motion. That is, the sun rises in the west and sets in the east.
Answer from Ivan Vasilievich changes his profession[guru]
It spins venereal, of course!
Answer from Dmitry Nizyaev[guru]
It depends on which pole you are watching ... But no matter how it rotates, it is not at all surprising. And why shouldn't she, in fact, rotate at least this way at least that way? Here Uranus is really amazing. It rotates completely not in the plane of its orbit, and this is a very unstable position. Strictly speaking, in the process of its formation, the planet has a chance to acquire the resulting rotation in absolutely any plane and in any direction. But if the plane of rotation of the planet does not coincide with the plane of its orbit, then tidal forces cause precession - approximately the same behavior as that of a top, whose axis is not vertical. Friction forces arise along the Coriolis arcs, and these forces gradually, turn by turn, change the direction of the axis of rotation. And the closer the plane of rotation is to the plane of the orbit, the less Corisolis forces interfere in the process - which leads sooner or later to balancing this plane. Therefore, most planets rotate exactly or almost exactly in the plane of their orbit.
And Uranus rotates across! And one of two conclusions can be drawn from this: either Uranus is much younger than the rest of the planets of the system, or the plane of its rotation is accidentally so close to the perpendicular to the orbit that the Coriolis forces balance each other. Figuratively speaking, the planet found itself in such precise equilibrium that it still cannot decide which side it should fall on. A rare case, it turns out!
Answer from Nikolay Gorelov[guru]
Look at the sky. The sun scratches it clockwise, which means our Earth is counterclockwise. Then Venus spins clockwise, that is, not like people.
Answer from 3 answers[guru]
Hey! Here is a selection of topics with answers to your question: Is it true that Venus rotates counterclockwise ???
I was interested in the topic of what rotates clockwise and what rotates counterclockwise. Very often you can find in the world a lot of things based on vortices, spirals, twists, having a right spin of rotation, that is, twisted according to the rule of the gimbal, the rule of the right hand, and the left spin of rotation.
Spin is called the proper angular momentum of a particle. In order not to complicate the note with theory, it is better to see once. Slow waltz element - right spin turn.
For many years there has been a discussion among astronomers about the direction in which the spiral galaxies rotate. Do they rotate, dragging spiral branches with them, that is, twisting? Or do they rotate with the ends of the spiral branches forward, unwinding?
At the present time, however, it is becoming clear that observations support the hypothesis of the twisting of the spiral branches during rotation. The American physicist Michael Longo was able to confirm that most of the galaxies in the Universe are oriented to the right side (right spin), i.e. rotates clockwise when viewed from its north pole.
The solar system rotates counterclockwise: all planets, asteroids, comets rotate in the same direction (counterclockwise, when viewed from the north pole of the world). The sun rotates on its axis counterclockwise when viewed from the north pole of the ecliptic. And the Earth (like all the planets of the solar system, except Venus and Uranus) rotates around its axis counterclockwise.
The mass of Uranus, sandwiched between the mass of Saturn and the mass of Neptune, under the influence of the rotational moment of the mass of Saturn, got clockwise rotation. Such an impact from Saturn could have occurred for the reason that the mass of Saturn is 5.5 times the mass of Neptune.
Venus rotates in the opposite direction than almost all planets. The mass of the planet Earth spun the mass of the planet Venus, which got clockwise rotation. Therefore, the diurnal periods of rotation of the planets Earth and Venus should also be close to each other.
What else is spinning, spinning?
The snail's house spins clockwise from the center (i.e., rotation here goes with a left spin, counterclockwise).
Tornadoes, hurricanes (winds centered in the area of the cyclone) blow counterclockwise in the Northern Hemisphere and obey the centripetal force, while the winds centered in the area of the anticyclone blow clockwise and have centrifugal force. (In the Southern Hemisphere, everything is exactly the opposite.)
The DNA molecule is twisted into a right-sided double helix. This is because the backbone of the DNA double helix is composed exclusively of right-handed deoxyribose sugar molecules. Interestingly, during cloning, some nucleic acids change the direction of twisting of their helices from right to left. In contrast, all amino acids are twisted counterclockwise to the left.
Flocks of bats, flying out of caves, usually form a "dextrorotatory" vortex. But in caves near Karlovy Vary (Czech Republic), for some reason, they circle in a spiral, twisted counterclockwise ...
When one cat sees sparrows (these are her favorite birds), the tail turns clockwise, and if these are not sparrows, but other birds, then it turns counterclockwise.
And if we take Humanity, then we see that they are going counterclockwise: all sporting events (auto racing, horse races, running at the stadium, etc.) After some centuries, athletes noticed that it is much more convenient to run this way. Running the stadium counterclockwise, the athlete with his right foot makes a wider step than he would have done with his left, since the range of motion of the right foot is several centimeters larger. In most armies of the countries of the world, a circle is turned over the left shoulder, that is, counterclockwise; church rituals; the movement of cars on the roads in most countries of the world, with the exception of the UK, Japan and some others; at school the letters "o", "a", "b", etc. - from the first grade they teach to write counterclockwise. In the future, the overwhelming part of the adult population draws a circle, stirring with a spoon with sugar in a mug counterclockwise.
And what follows from all this? Question: Is counterclockwise rotation natural for humans?
As a conclusion: the Universe moves clockwise, but the solar system is against, the physical development of all living things is clockwise, consciousness is against.
I was interested in the topic of what rotates clockwise and what rotates counterclockwise, and that's what I discovered.
The galaxy rotates on clockwise, when viewed from its north pole, located in the constellation Coma.
The rotation of the solar system occurs against clockwise: all planets, asteroids, comets rotate in the same direction (counterclockwise when viewed from the north pole of the world).
The sun rotates on its axis against of the hour hand when viewed from the north pole of the ecliptic. And the Earth (like all the planets of the solar system, except Venus) rotates around its axis against clockwise.
It is possible that it is this rotation of the Galaxy (clockwise) and the Solar system (counterclockwise) that is displayed on the eight-pointed swastika kolovrat (right rays), inside which there is another eight-pointed swastika kolovrat (left rays). link
An interesting experience was observed by travelers crossing the equator. If you throw a match or a twig into a funnel filled with water, then in the Southern Hemisphere it turns clockwise, in the Northern Hemisphere - against, and at the equator it stands. link
According to the law of right-hand traffic, adopted in our country, the circular movement goes counterclockwise. With the oncoming traffic of two cars rushing at high speeds, an air vortex rotating counterclockwise appears. And when there are a huge number of such meeting pairs, then these vortices can cause a tornado. link
The main rotors of helicopters in different countries rotate in different directions. That is, in some countries, helicopters are made with a clockwise rotating screw, and in others - counterclockwise. If you look at the helicopter from above, then:
in America, Germany and Italy, the screw turns counterclockwise.
in Russia and France - clockwise. link
Flocks of bats, flying out of caves, usually form a "dextrorotatory" vortex. But in caves near Karlovy Vary (Czech Republic), for some reason, they spin in a spiral, twisted counterclockwise ... link
When one cat sees sparrows (these are her favorite birds), the tail turns clockwise, and if these are not sparrows, but other birds, then it turns counterclockwise. link
But the dog, before going on business, must turn counterclockwise. link
The spiral staircases in the castles were twisted clockwise (if viewed from below, and if viewed from above, then counterclockwise) - so that it would be inconvenient for the attackers to attack when they climbed. link
The DNA molecule is twisted into a right-sided double helix. This is because the backbone of the DNA double helix is composed exclusively of right-handed deoxyribose sugar molecules. Interestingly, during cloning, some nucleic acids change the direction of twisting of their helices from right to left. In contrast, all amino acids are twisted counterclockwise to the left.
There is a DNA spiral in space: on the Milky Way, scientists have discovered a nebula in the form of a DNA double helix. link
But the spirals of electric bulbs made in Russia are twisted to the left (unlike foreign ones, which are twisted in the same way as the DNA spiral, to the right). The question arises: is it not harmful?
Venus is the second planet of the solar system. Its neighbors are Mercury and Earth. The planet was named after the Roman goddess of love and beauty - Venus. However, it soon turned out that the planet's surface had nothing to do with the beautiful surface.
Knowledge about this celestial body was very scarce until the middle of the 20th century due to dense clouds hiding Venus from the view of telescopes. However, with the development of technical capabilities, mankind has learned many new and interesting facts about this amazing planet. Many of them raised a series of questions that have not been answered so far.
Today we will discuss hypotheses explaining why Venus rotates counterclockwise, and tell interesting facts about it, known to planetary science today.
What do we know about Venus?
In the 60s, scientists still had a glimmer of hope that the conditions for living organisms. These hopes and ideas were embodied in their works by science fiction writers who narrated the planet as a tropical paradise.
However, after the spaceships were sent to the planet, the scientists who provided the first idea about them came to disappointing conclusions.
Venus is not only uninhabitable, it has a very aggressive atmosphere that destroyed several of the first spaceships sent into its orbit. But despite the fact that communication with them was lost, the researchers still managed to get an idea of the chemical composition of the planet's atmosphere and its surface.
Also, researchers were interested in the question of why Venus rotates counterclockwise, just like Uranus.
Twin planet
Today it is known that Venus and Earth are very similar in physical characteristics. They both belong to the terrestrial group of planets like Mars and Mercury. These four planets have few or no satellites, have a weak magnetic field, and lack a ring system.
Venus and Earth have a similar mass and are only slightly inferior to our Earth), and also rotate in similar orbits. However, this is where the similarities end. The rest of the planet is in no way like Earth.
The atmosphere on Venus is very aggressive and is 95% carbon dioxide. The planet's temperature is absolutely unsuitable for life, as it reaches 475 ° C. In addition, the planet has a very high pressure (92 times higher than on Earth), which will crush a person if he suddenly decides to walk on its surface. They will destroy all living things and clouds of sulfur dioxide, creating precipitation from sulfuric acid. The layer of these clouds reaches 20 km. Despite its poetic name, the planet is a hellish place.
What is the speed of rotation of Venus around its axis? As it turned out as a result of research, one Venusian day is equal to 243 Earth days. The planet rotates at a speed of only 6.5 km / h (for comparison, the speed of rotation of our Earth is 1670 km / h). Moreover, one Venusian year is 224 Earth days.
Why does Venus rotate counterclockwise?
This question has been of concern to scientists for more than a decade. However, until now no one has been able to answer it. There have been many hypotheses, but none of them has yet been confirmed. Nevertheless, we will consider a few of the most popular and interesting ones.
The fact is that if you look at the planets of the solar system from above, Venus rotates counterclockwise, while all other celestial bodies (except Uranus) rotate clockwise. These include not only planets, but also asteroids and comets.
When viewed from the north pole, Uranus and Venus rotate clockwise, while all other celestial bodies rotate against it.
Reasons for counterclockwise rotation of Venus
However, what caused this deviation from the norm? Why does Venus rotate counterclockwise? There are several popular hypotheses.
- Once upon a time, at the dawn of the formation of our solar system, there were no planets around the sun. There was only one disk of gas and dust, which rotated clockwise, which eventually passed on to other planets. A similar rotation was observed for Venus. Soon, however, the planet likely collided with a huge body that slammed into it against its rotation. Thus, the space object seemed to "launch" the movement of Venus in the opposite direction. Perhaps Mercury is to blame for this. This is one of the most interesting theories, which explains several surprising facts at once. Once upon a time, Mercury was probably a satellite of Venus. However, he later collided with it tangentially, giving Venus part of its mass. He himself flew into a lower orbit around the Sun. That is why its orbit has a curved line, and Venus rotates in the opposite direction.
- Venus can be rotated by the atmosphere. Its layer width reaches 20 km. Moreover, its mass is slightly less than that of the earth. The density of Venus's atmosphere is very high and literally squeezes the planet. Perhaps it is the dense atmosphere that rotates the planet in a different direction, which explains why it rotates so slowly - only 6.5 km / h.
- Other scientists, observing how Venus rotates around its axis, came to the conclusion that the planet is turned upside down. It continues to move in the same direction as the other planets, however, due to its position, it rotates in the other direction. Scientists believe that a similar phenomenon could have been caused by the influence of the Sun, which caused strong gravitational tides, combined with friction between the mantle and the core of Venus itself.
Conclusion
Venus is a terrestrial planet, unique in nature. The reason it spins in the opposite direction is still a mystery to humanity. Perhaps someday we will solve it. In the meantime, we can only build assumptions and hypotheses.
