Clouds are generated at or just below the tropopause region, which lies between the troposphere and the stratosphere. A new mission competing for selection under NASA's Discovery Program would try to untangle the mysteries of Neptune's strange moon Triton. Sometimes Neptune is even farther from the Sun than dwarf planet Pluto. Neptune's atmosphere is essentially the same as that of Uranus in terms of its basic composition. Pluto (a dwarf planet) may have an appreciable atmosphere, but perhaps only when its highly elliptical orbit is closest to the Sun. The Great Dark Spot of the planet Neptune is actually a depression in its atmosphere that is surrounded by high cirrus type of clouds. Neptune is a gas giant, so it has a very thick atmosphere. Uranus has a surface temperature of 58 K. no significant internal heat source. The eighth and last planet in the solar system, Neptune has an atmosphere more comparable with Uranus than with Saturn and Jupiter.
