What gases make up Neptunes atmosphere?
Neptune’s thick atmosphere consist of 74% hydrogen, 25% helium and about 1% methane. The atmosphere merges into the planet’s mantle. Neptune’s atmosphere has icy clouds and enormous storms. These features change rapidly because of tremendous winds that whip around the planet. Neptune has the fastest winds in our Solar System. Icy particles of methane in the outer parts of its atmosphere give Neptune its deep blue color; methane absorbs red light. http://www.enchantedlearning.com/…/atmosphere.shtml Neptune’s atmosphere is made up of hydrogen, helium, and methane. Like Earth’s atmosphere, Neptune’s has clouds and storm systems that revolve around the planet, but with wind speeds of 300 m/sec (700 mi/hr), and clouds of frozen methane. http://www.nasm.si.edu/…/nept_atm
