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.
Venus is often called the twin planet to Earth because 1) it has a similar radius/size, 2) is has a similar mass, 3) it has a similar density and 4) it has an atmosphere.ars is another example of a secondary atmosphere from outgassing (therefore, we know that Mars had an early epoch of tectonic activity). However, unlike the Earth or Venus, the atmosphere is very thin, about 1% the mass of Earth's atmosphere. Its composition is 95% CO2, 3% N2, 2% Ar and less than 1% O2.
