Quick Answer

Mercury has the fastest orbit around the Sun, completing a year in just 88 Earth days.

The Full Story

Mercury has the shortest year and the fastest orbit around the Sun. It completes one orbit in about 88 Earth days, much faster than any other planet. Because it is so close to the Sun, gravity pulls it into a very quick path. This makes Mercury a classic example of how orbital speed depends on distance from the Sun.

Key Facts

1.Mercury’s year lasts about 88 Earth days
2.It is the closest planet to the Sun
3.Closer planets orbit faster because of stronger gravity
