The equatorial rotational speed for the planet Mars is about 868.22 km/hr or 540 mph. This is far slower than the rotation of Earth (1674.4 km/hr), giving the two planets roughly the same period of rotation (Mars day = 24.6 Earth hours).
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
Mars spins slower than earth
Earth spins faster than Venus.Here's a link for information:http://www.nasa.gov/worldbook/venus_worldbook.html
A "Day" relates to the rotation of the planet. The giant Saturn spins around, or rotates, once every 10 hours and 45 minutes. So it's "Day" is only 10 hours 45 minutes (earth hours) long. Whereas Earth spins slower so its day is longer.
24 hours
Mars is about the closest to the Earth's rotation among the planets in our solar system. Earth spins in 24 hours; Mars takes 24 hours 40 minutes.
The Earth's rotation
1.Earth has Strong Gravity. 2.Earth doesn't spins so fast!
Earth.
it spins and aprox. 100km every DAY
It depends on what latitude you are at but the equatorial rotational speed is 1,670.5 km/hr
