Earth to Mars are 8 planets with varying atmospheres. Venus has a dense one, Pluto's is incredibly thin, and the others fall in between

Mercury's atmosphere is very thin, almost negligible, with a scale height of just 2.6 kilometers (1.6 miles) which means atmospheric pressure decreases every 2.6 kms as we go up

Its scale height is approximately 15.9 kilometers (9.9 miles). This means that the atmospheric pressure decreases significantly with altitude over a relatively short distance

Earth's scale height is about 8.5 kilometers (5.3 miles). This means that the atmospheric pressure decreases by a factor of e for every 8.5 kilometers you go up

Its scale height is approximately 10.8 kilometers (6.7 miles). Despite this, it is still thick enough to have a noticeable effect on weather and climate

Jupiter has a massive and deep atmosphere. Its scale height is around 27 kilometers (16.8 miles), making it much thicker than Earth's atmosphere

Saturn's atmosphere is also quite thick, with a scale height of approximately 59.5 kilometers (37 miles). It is substantially thicker than Earth's atmosphere

Uranus has even thicker atmospheres, with scale heights of about 27 kilometers (16.8 miles)

Neptune has a very thick atmosphere with a scale height of 19 kilometers (11.8 miles)
