Yes. Each moon revolves around its own planet. Our Moon revolves around Earth.
One year for planet Earth, different times for each of the other planets.
All of them. A few satellites are tidally locked to their primary (luna for example), but all the planets rotate.
The Sun does not rotate around the Earth, nor does the Earth rotate around the Sun. The Earth revolves around the Sun each year, and each body rotates about its own axis: once a day for the Earth, once in about 25 days for the Sun.
The asteroids in the asteroid belt do move around the Sun, but they don't rotate as a single unit like a planet does. Each asteroid has its own orbital path and speed, so there isn't a specific speed at which the asteroid belt as a whole rotates.
Unlike their orbits around the sun - which was inherent in the way the planets were formed - their rotation speeds and axis of rotation is random and is dependent on each planet's history of collisions.
Is this question asking "how many degrees does the planet rotate in one hour?" In one day (24 hours), the planet makes a full rotation of 360 degrees. So each hour it would rotate 360/24 = 15 degrees.
To find the number of revolution days of a planet, you can use the formula: revolution days = orbital period / rotation period. The orbital period is how long it takes for the planet to complete one orbit around the sun, while the rotation period is how long it takes for the planet to rotate on its axis. This formula will give you the number of days it takes for the planet to complete one full rotation around its axis.
Here are the approximate rotation periods for each planet in the solar system: Mercury: 59 Earth days Venus: about 243 Earth days (retrograde rotation) Earth: about 24 hours Mars: about 24.6 hours Jupiter: about 10 hours Saturn: about 10.7 hours Uranus: about 17.2 hours Neptune: about 16 hours
The Sun does not rotate around the Earth, nor does the Earth rotate around the Sun. The Earth revolves around the Sun each year, and each body rotates about its own axis: once a day for the Earth, once in about 25 days for the Sun.
If the moon were to rotate twice during each revolution, the tides on the Earth would appear different. Also, the moon itself would show its far side rather than having the same side facing the planet all the time.
