Every time the earth rotates, the earth we are on experiences a day's time, and the earth revolves around the sun, which is a year's time, which is the unit of time that we humans have become accustomed to, most people may have lived under the "laws" of nature, and few people have even thought: "Why do we have to follow this pattern?"
This is because as the Earth revolves around the Sun, the angle and time of rotation are fixed, resulting in a 24-hour day, a 365-day year.
In fact, the Earth is not the only planet in the solar system that revolves around the sun, nor is it the only planet whose rotation time is not equal to the orbital time, there are dozens of planets in the solar system, including nine large planets and hundreds of dwarf planets, all of which are different in size and orbit, and naturally their rotation and rotation speed are also different.
So, what are the laws of the revolution and rotation of these planets?
1. The speed of rotation and revolution.
The speed of rotation and revolution refers to the time required for the planet to rotate and the planet to revolve around the sun, usually the rotation time of the planet with a slightly slower rotation speed will be a little longer than the rotation time, and the rotation time of the planet with a faster rotation speed will be a little shorter than the rotation time, because the planets are rotating and rotating in the same direction, and the rotation speed is affected by gravity.
So if a planet rotates slowly, it must be an outerer planet that is subject to the gravitational pull of most of the inner planets as it orbits, which causes it to take longer to rotate around one cycle.
At the same time, since the orbit of the planets around the sun is not formed in infinite space, but moves around the gravitational field of the sun, the planets will continue to be affected by the gravitational pull of the sun when they rotate, causing their rotation speed and revolution time to change slightly.
Of the nine planets in the solar system, the first four and the last three are orbiting in the plane that orbits around the sun, and Jupiter is the furthest away from this plane.
But when we divide the inner and outer sides of the planets, Jupiter, Saturn, Uranus, and Neptune are all planets located on the outer side of the planet, that is, the planets that are farther away from the Sun.
Therefore, according to the rotation and revolution speed of these planets, the gravitational attraction of the planets during the revolution and rotation is well confirmed.
Among these planets, Saturn is the planet with the fastest orbit and the shortest rotation time of all planets, to be precise, this planet only needs 10.5 hours to rotate a cycle, but for it, it only takes 29.5 years to complete one revolution each time.
On the other hand, Uranus is the planet that takes the longest time to rotate of all the large planets, taking 14 hours to orbit itself, but only needs to orbit the Sun for more than 84 years.
On the inner side of the planet, there is Venus, the slowest planet with the slowest rotation, but it is also a planet located on the outer side of the planet.
Venus is located on the outer side of the Earth and is the closest planet to the Sun, but her rotation speed is even faster than that of Uranus, and it takes 243 Earth days to rotate one week, that is, 215 Earth days, but it only takes 225 days to revolve around the Sun, which creates the strange phenomenon that Venus will have a day longer than a year, so why does Venus rotate longer than other planets?
How did Venus form?
2. Complex rotation speed.
The speed of rotation directly reflects the speed of the change of the sunshine area and temperature difference on the planet, thus affecting the living environment of the creatures on the planet, so the extremely slow rotation speed of Venus means that the diurnal change of Venus is very slow, and the temperature difference between day and night is also very small.
Venus's rotation speed is 6.5 kilometers in one hour, which means that a day on Venus takes 243 days on Earth, compared to 225 days in a year on Venus.
This speed of rotation is unique because Venus is the only planet in the solar system that rotates in the opposite direction to the other planets, which means that Venus is going 200 kilometers east every hour, but the other planets are moving west.
Therefore, even if you look at the Sun from Venus, you will find that the Sun "rises" from the west and "sets" in the east, so the East and West concepts of Venus are opposite, and the way time passes on Venus is also different from that of Earth, which in turn has an important connection with the formation of the solar system.
Mankind has not yet reached a definitive conclusion about the formation and evolution of the solar system, but in either case, it should be possible to explain why Venus has such a strange rotation phenomenon.
In most cases, the formation of the solar system was caused by the gravitational pull of the primordial sun and the interaction between the matter inside, and in this case, the reason for Venus's slow rotation may be due to the fact that Venus collided with nearby celestial bodies a long time ago, slowing down Venus's rotation.
Such a collision causes the angular momentum of Venus's rotation to be dissipated, while making Venus's orbit around the Sun shorter.
On the other hand, the interior of the solar system is a mass of nebula matter that has undergone condensation and formed the sun, and then a large amount of interstellar matter slowly begins to move around the sun, and after condensation, asteroids are formed, and finally some asteroids interact with each other or with the sun for some reason to form larger planets, and the collision between celestial bodies is one of them.
In this understanding, other planets in the solar system are gradually formed by the interaction of these orbiting objects, so the reason for the slow rotation speed of Venus may be that it constantly collides with other celestial bodies, which makes the rotation speed of Venus gradually slow down.
This is also related to the collision of orbital objects near Venus, especially the formation of more colorful volcanoes and craters.
In the latest view, the formation of the solar system is caused by the explosion of a star near the solar system, and in this view, the shock wave generated by the explosion of the star will also have an impact on the formation and evolution of the planets in the solar system, which also explains the rotation of Venus.
3. The rotation of Venus.
The rotation of Venus is unique in the solar system, which provides important clues for scientists to study the formation and evolution of the solar system, but the current research on the early history of Venus is still difficult because human technology on Earth has not been able to make detailed observations of the planets on Earth.
But the rotation of Venus has also led scientists to speculate about its early history, and some people believe that Venus also once had life, and the ecological environment on Venus is similar to that on Earth, which is also confirmed by their size and density.
Therefore, whether Venus's rotation speed will be the same as that on Earth as we now imagine is yet to be verified by future scientists through exploration.
But Venus's extremely slow rotation brings new challenges and possibilities for people to explore and colonize other planets, with a year of only 225 days but 243 long nights, and during the day, Venus is also very hot, reaching around 400 degrees Celsius.
Humans or other creatures cannot exist in this high temperature, but this does not mean that there is no life on Venus, and we still have a clear understanding of life in outer space, but one thing is certain, life in outer space will certainly not adapt to the harsh environment like life on Earth, and some people believe that life in outer space may be the most powerful existence in the galaxy.
At the same time, the rotation of Venus, contrary to other planets, will also cause great inconvenience to humans when they land on Venus, which also feels the challenges brought by life in outer space.
However, life in outer space is also a very exciting thing for human beings to explore the unknown, which also stimulates people's enthusiasm for exploring life in outer space, and also makes people have more imagination of the wonderful life in outer space.
epilogue
The rotation of Venus has brought great differences in the time and living environment of other planets located outside the Earth, and the rotation of Venus has also provided clues for scientists to study the formation of the solar system.
And this is what scientists have been pursuing, hoping to make human beings have a more accurate understanding of the formation of the solar system through their own efforts.
