How Long Is a Year?

One trip around the Sun for each planet, in Earth days

A year is the time a planet takes to go once around the Sun. Earth needs about 365 days.
The farther a planet is from the Sun, the longer its path and the slower it moves, so its year is much longer.
Neptune needs about 59,800 Earth days, which is almost 164 Earth years, to go around the Sun once.
