Venus is the second planet which is closest from the sun after Mercury. Venus is also the planet closest to the earth and has the nickname of the Goddess of Love, the morning Star and the Star of the Twilight.
Do You know why Venus is called as one of the planets most unique in our solar system?
Curious?
Want to know why?
Here’s why:
There are several reasons why Venus is called as one of the planets most unique in our solar system. Some of them is because:
1. The direction of rotation of Venus in a clockwise direction
If other planets in our solar system rotate on their axes in opposite direction clockwise (viewed from the north pole of the ecliptic), then Venus is the only planet that the direction of rotation is clockwise or often called retrograde.
Whether its impact?
Surely if we can live there, then we’ll watch the sun rise in the west and sets in the east. Strange, isn’t it? Yeah, but don’t imagine a day in there the same with a day in the earth, i.e. 24 hours. Due to the rotation of Venus is a very slow-which is only 65 km/h at the equator (compare with the speed of rotation of the earth at the equator is 1670 km/h) then it is the time of day on Venus will be very long all the time at night.
Why is the direction of rotation of Venus in a clockwise direction?
First change the direction of rotation is presumably due to the collision of a very terrible so as to change the direction of rotation of Venus with immediately. But then be aware that what actually happens is the change in the pole of rotation of Venus where the north pole is in the south and the south pole to the north. The angle of inclination of the north pole of rotation of Venus on the north pole of the ecliptic reaches 177o or almost reach 180o (the perfect counterpoint), is very large compared to the Earth which is only 23.5 o. Because the north pole and the south pole of Venus “swap position” then the direction of rotation the rotation of Venus seen from the south pole of rotation of Venus (which is now located at the top) to be clockwise. But actually, if viewed from the north pole the rotation of Venus (which now exists under) the direction of rotation is fixed in the opposite direction of clockwise.
Why is the angle of inclination of the north pole Veus can be so large?
Some theories say that at the beginning of the formation of the solar system was still a lot of chunks of the rest of the formation of the planet. The Planet Venus young colliding with chunks and fragments of the chunk is ejected into space and form a natural satellite of Venus. So at first Venus has a natural satellites such as earth has a moon. After roughly 10 million years after the collision both very terrible in the side opposite to the collision first. The collision that is so fierce that this is what is suspected to be the cause of the migration of the north pole of rotation of Venus until it was almost upside down and result in a “change of direction” the rotation of Venus. “Change of direction” the rotation of Venus is the impact to the sustainability of the natural satellite of Venus. Because Venus rotates clockwise while the natural satellite of Venus surround Venus counterclockwise then slowly the force of gravity and tidal forces of Venus will attract the natural satellite of Venus in a spiral in the (approaching by Venus) so that eventually collide with Venus. If there is a collision of another fractions-fractions form a natural satellite of Venus back, then it’s natural satellite will not last long because it will collide again with Venus. However, if the natural satellite is too far away from Venus, then the gravitational force that the sun is going to pull it because Venus is the second planet closest to the sun. So until whenever Venus will never have a natural satellite, such as Mercury.
2. The period of rotation of Venus is longer than the period of revolution
Like the other planets, the period of rotation of Venus is the time needed by Venus rotates 360 ° around its axis. This period is often referred to as the period of the sidereal. The period of rotation of Venus is the period of rotation of the slowest among the other planets in the solar system, namely 243 earth days (in the picture above from the position (1) to (3)). While the period of revolution of Venus around the sun with orbits approach the circle (unlike other planets are elliptical in shape) is for 224,65 earth day or on the picture above from the position (1) back to (1).
At first glance it looks one day on Venus is longer than one year. Is it true?
Apparently not. Due to the rotation of the unique of Venus in a clockwise direction then the day of the sun (day sinodis) Venus be faster than the day siderisnya. One day the sun Venus ever 116,75 earth day or on the picture above from the position (1) to (2). That is, one year on Venus is equal to 1.92 days the sun. Just imagine if we lived in Venus, we’re going to a birthday every 2 days, but 1 day we had to wait for about almost 4 months, two moon two moon night.
