Answer #1

Answer:

This can be described by Kepler's second law of planetary motion which states: "A line from the planet to the Sun sweeps out equal area in equal times. Farther the planet from the sun, less will be its rotational speed and nearer the planet to the sun, higher will be its rotational speed." That is why, inner planets or inner orbiters have higher rotational speeds than their outer counterparts. The speed of the planets are given below in the table.

Planets Rotational Speed Around Sun
Mercury 47.87 km/s
Venus 35.02 km/s
Earth 29.78 km/s
Mars 24.077 km/s
Jupiter 13.07 km/s
Saturn 9.69 km/s
Uranus 6.81 km/s
Neptune 5.43 km/s
