Neptune is the outermost planet of the gas giants. It has an equatorial
diameter of 49,500 kilometers (30,760 miles) and is the eighth planet from the

times the diameter, 30 times the distance from the sun, 17 times as massive, and
0.3 times the density. Neptune travels around the Sun in an elliptical orbit at
an average distance of 4.504 billion km (2.799 billion miles). Neptune consists
