Absolutely. Spin creates centrifugal force, which actually works against gravity. When a object on a planet spins with the planet, the spin of the planet is constantly trying to fling said object off into space, where as gravity is constantly forcing the object toward the spinning body. If the spin became so great that it overcame the gravitational pull, the object would be flung into space. While spin does not actually affect the gravity of an object, it can reduce the amount of gravity an object on the surface experiences.
Yes, but all at different rates. Venus takes the longest at 243 days, Jupiter spins the fastest, taking only 9h 55mins.
As with any object, the gravity of a planet is due to its mass.
No, it results from its mass.
yes planets spin
Yes
Of what? orbit: Mercury spin: Jupiter wind: Neptune
The sun spins.
They don't. Uranus spins on a "sideways" axis with retrograde spin. Venus also has a retrograde spin. Most spin in the same direction though. This is probably because of how the Solar System was formed, from a spinning disc of material.
This is known as prograde rotation, all of the planets spin in this direction apart from Venus and Uranus. Venus and Uranus spin clockwise when viewed from above the north pole, this is known as a retrograde spin.
There is only Venus, and Uranus. Both spin opposite direction of Earth.
All the planets that we know about spin, yes. Some spin faster or slower, or on a different axis, but they all spin.
no
no, all planets spin and all planets in our solar system revolve around the sun.
All planets spin on their axes as well as orbiting the Sun.
All planets do, however, mercury is quite slow.
Venus Uranus Pluto all spin backwards (clockwise) Mercury, Earth, Mars, Jupiter, Saturn, Neptune all spin forwards (counter-clockwise)
Yes.
rotation
All of the planets spin like a top, even the Sun!
Yes, all planets spin like spinning balls, some faster than others, however.
Because It Has To Spin Like Planets Do
Yes, all planets that we know of have at least some spin - their rotation on the axis being the planet's day. In our solar system Jupiter spins the fastest - with a day under 10 hours long.
