The only planet which doesn't have an atmosphere is Mercury.

Mercury is the only planet without an atmosphere in the traditional sense; instead, it has an exosphere, which is made up of gases such as oxygen, helium, and hydrogen that are released from the planet's surface as well as those that are taken in from the solar wind.

Venus's atmosphere is extremely thick, mostly made of carbon dioxide, making it impossible to see the planet's surface without sending a probe through it.

Naturally, the atmosphere of Earth is mostly composed of oxygen and nitrogen.

Mars has a very thin atmosphere made mostly of carbon dioxide.

Gas and ice giants Jupiter, Saturn, Uranus, and Neptune have substantial atmospheres primarily composed of hydrogen and helium.
