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.
Solar light pushes the atmospheric gases away from the Sun, creating a comet-like tail behind the planet. The existence of a Mercurian atmosphere had been contentious before 1974, although by that time a consensus had formed that Mercury, like the Moon, lacked any substantial atmosphere. This conclusion was confirmed in 1974 when the unmanned Mariner 10 spaceprobe discovered only a tenuous exosphere.
