The orbital period is 29.447498 years and the rotational period is 0.44401 days.
These values are approximate, one can never know the exact figures.
The rotation on its own axis is normally what we call the planet's 'day'. On earth, of course, a day is thought of as equalling 24 hours. This refers to a Solar Day (ie the time for the earth to rotate once on its axis so that the sun appears again in exactly the same place in the sky the next day. However, this 'day' does not really represent the earth rotating once on its axis (360 degrees), because the earth will have moved a little round the sun in a day, and therefore after the earth has rotated exactly one revolution the sun does not quite reach that exact same place in the sky. Therefore, one day on earth (as measured by its rotation of 360 degrees exactly) is not quite a full day, but around 23 hours 56 minutes (23.95 hours). The other planets' 360 degree rotations are as follows: Mercury: Rotation about its axis = 1408 hours (about 59 days) Venus: Rotation about its axis = 5832 hours (about 243 days - which is longer than its year of 226 days!) Earth: Rotation about its axis = 23.93 hours Mars: Rotation about its axis = 24.62 hours Jupiter: Rotation about its axis = 9.92 hours Saturn: Rotation about its axis = 10.66 hours Uranus: Rotation about its axis = 17.24 hours Neptune: Rotation about its axis = 16.11 hours Pluto is now not recognised as a major planet, but for the sake of completion I'll include the data. Rotation about its axis = 153.3 hours So the slowest planet is Venus whose period of rotation about ts own axis is longer than its year. The fastest is Jupiter - and its quick rotation gives it a squashed appearance because of 'centrifugal force' making the planet bulge out at the equator.
The planet Mercury completes one revolution in its orbit around the Sun in about 88 Earth days (87.969 days, to be more exact). This is about 0.241 Earth years.
It is impossible to determine the exact number of rocks on Mars as they are distributed across the planet's surface. The number of rocks on Mars would be vast and vary in size from small pebbles to large boulders.
The exact number depends on the individual planet, and the exact shape and eccentricity of its orbit. The one general statement that can be made for every planet is that when it's farthest from the sun, it's moving at the slowest speed relative to the sun of any point in its entire orbit.
You never see the far side of the moon. Somewhat coincidently the moon has an angular rotation as the earths rotation, and therefore the same side of the moon is always facing earth. The far side is never seen. To the extent that the rotations are not exact, there may be a slight variation over many, many years.
The third planet from the Sun is Earth. It takes 24 hours for the Earth to make one full rotation on its axis.
Retrograde motion refers to the clockwise rotation of a planet as opposed to the more common counterclockwise rotation. This phenomenon is rare in our solar system, with Venus being the only planet that exhibits retrograde rotation. The exact reasons for Venus's retrograde rotation are not fully understood but may be due to past impacts or gravitational interactions with other celestial bodies.
4.
The exact number of rotations of a planet is equal to one rotation per revolution. This is because the time it takes for a planet to complete one orbit around its star is typically the same as the time it takes for the planet to rotate once on its axis.
There is no exact date when the meteor hit Mercury, but it was millions of years ago. It was strong enough to cause the previously stagnate planet, to begin its rotation.
No i am sorry to say mars is not an exact sphere. the rocks and boulders and everything on the planet is not an exact sphere
When performing a rotation, you do not need to know the exact coordinates of the center of rotation. All you need is the angle of rotation and the shape or object being rotated.
24 hours to be exact.
24 hours! To be exact, it's about 4 minutes less than that.
To establish an exact position on the planet.
Latitude and Longitude specify any location on the planet.
Saturn. (The exact number of rings depends on how you count them.)
