What is the Mercurys atmosphere compared to earth?
Mercury's atmosphere is extremely thin compared to Earth's. It is composed mostly of oxygen, sodium, hydrogen, helium, and potassium, but its overall density is about 100 trillion times less than Earth's atmosphere. Mercury's weak gravity isn't strong enough to retain a thick atmosphere like Earth's.
