it takes 7 years for Eris to orbit 1 rotaion
23 hours, 56 minutes.
Jupiter isn't solid, so it undergoes what's called "differential rotation". A little under 10 hours is correct for pretty much the whole planet, but the equatorial region rotates a little faster than the rest of it: about 9 hours and 50 minutes at the equator, vs. about 9 hours and 55 minutes nearer the poles.
The third planet from the Sun is Earth. It takes 24 hours for the Earth to make one full rotation on its axis.
Everyone knows that it takes the Earth 24 hours to make one rotation. Saturn on the other hand, takes 10 hours and 45 minutes to complete one rotation.
The planet that takes 88 days to make one trip around the sun is Mercury. It is the smallest planet in the solar system.
Rotational period is the time it takes for a planet to make one full rotation around it's axis. Pluto takes about 153.3 hours to make one full rotation - or about 6.39 Earth days.
The time a planet takes to make a single trip around the sun is called its orbital period or year.
The planet Mars, which is the fourth planet from the sun, takes 1.88 Earth years to make one full orbit around the sun.
