Portraits of the terrestrial planets with atmospheres. Compare the thin wisp of atmosphere on Mars with the swirling weather patterns of the Earth and the thick clouds of Venus.
Color indicates elevation in these animations. For Venus and Mars, black and purple represent the lowest regions, while red and white represent the highest areas. For the Earth, deep blue represents the lowest ocean floors, while red represents the highest mountains.
