Neptune's revolution period is 60,190 Earth days. This is equal to 164.8 Earth years. This is how long it takes Neptune to make one revolution around the sun.
Not only is Neptune's revolution period interesting, but there are also other facts that make Neptune worthy of study. It takes Neptune 19.1 Earth hours to make one rotation and its average temperature is around -373 degrees Fahrenheit. Its atmosphere is made of 74 percent hydrogen and 25 percent helium, with the other 1 percent being methane. Neptune, like Saturn, has rings, although Neptune's rings are more narrow than those found on Saturn.
