Neptune. Computer artwork of a possible scene below clouds on the planet Neptune. Neptune,a gas giant,is the eighth planet from the Sun. The large distance from the Sun means Neptune's outer layers are around -218 degrees Celsius. Most of the atmosphere is hydrogen and helium,with traces of water and methane. The temperature and pressure rise with depth,and the atmosphere merges into a liquid region of rock,water,methane and ammonia. Deep below this is a rocky core. From space,Neptune appears blue due to the absorption of red light by atmospheric methane. Neptune has the fastest winds in the solar system | |
