Atmosphere of Neptune. Uranus, Neptune and Pluto

Being so far from the Sun, Neptune receives very little heat from its star, so that its surface temperature is about 218 ° C below zero. However, Neptune has an internal heat source that produces huge climate systems around the planet.

Bright elongated clouds, similar to Earth's cirrus clouds, have been observed in the upper atmosphere of Neptune. At low northern latitudes, the Voyager spacecraft captured images of cloud banks that cast their shadow over the lower cloud layers.

The strongest winds measured on any of the planets of the solar system are those of Neptune. Most of these winds blow westward, in the opposite direction to the planet's rotation. Near the Great Dark Spot, winds blow at almost 2,000 kilometers per hour.

Uranus and Neptune have little hydrogen compared to the two giants; Uranus, also with a series of rings around it, is distinguished because its axis of rotation forms an angle of 8 ° with the plane of its orbit.
