Temperature, Atmospheric Content, and Diameter of Planet
Neptune, the eighth and last planet from the sun, is one of the
coldest. But despite its great distance, the planet undergoes seasons much like
the Earth, creating warmer spots on the planet. The average temperature at the
top of the cloud tops is minus 346 degrees Fahrenheit
Neptune's atmosphere mainly consists of molecular hydrogen (H2)
80%, helium (He) 19% and methane (CH4)
1.5%
The diameter of Neptune is approximately 49,500 km. This makes
Neptune the 4th largest planet after Jupiter, Saturn, and
Uranus.
