Neptune

Neptune, the eighth and furthest planet from the Sun, is a very cold place. Its bluish color is caused by small amounts of methane gas in its atmosphere. The planet has moons and a very narrow, faint ring system.

Neptune's <a href="/neptune/lower_atmosphere.html&edu=high&dev=1">atmosphere</a> shows a striped pattern of <a href="/neptune/atmosphere/N_clouds_overview.html&edu=high&dev=1">clouds</a>. This cloud pattern is very similar to that of <a href="/jupiter/jupiter.html&edu=high&dev=1">Jupiter</a> and <a href="/saturn/saturn.html&edu=high&dev=1">Saturn</a>. Neptune even has a <a href="/neptune/atmosphere/N_clouds_GDS.html&edu=high&dev=1">Great Dark Spot</a> similar to Jupiter's <a href="/jupiter/atmosphere/J_clouds_GRS.html&edu=high&dev=1">Great Red Spot</a>. The Great Dark Spot of Neptune is thought to be a hole, similar to the hole in the <a href="/earth/Atmosphere/ozone_layer.html&edu=high&dev=1">ozone layer on Earth</a>, in the <a href="/physical_science/chemistry/methane.html&edu=high&dev=1">methane</a> cloud deck of Neptune.<p><small><em>Image courtesy of NASA</em></small></p>
