Venus has an atmosphere much denser than Earths, while Mars has an extremely thin atmosphere. All the gas giant planets (Jupiter, Saturn, Uranus, Neptune) have significant atmospheres, as their name implies! Even Pluto, which is not officially a planet anymore, has an atmosphere.
Atmospheres are similar (mostly hydrogen and helium), arranged in three layers on both planets, the major difference is that on Saturn the layers are thicker because of its weaker gravity. Like Jupiter, the planet also has bands, ovals, and flow patterns powered by convection.
