Astronomy/Atmosphere Pressure on Mars and Venus

Expert: - 4/6/2010


Question
What is the atmosphere pressure of these 2 planets? Are they higher than Earth's atmosphere pressure?

Answer
Hi Abigail,
The URL given below gives all planets' atmospheric pressure.  Venus is about 92 times the Earth and Mars is 0.007 that of the Earth, at
http://www.astro.uu.nl/~strous/AA/en/antwoorden/planeten.html#1_34
Question number 34.
So Venus is like being underwater at 3000 feet and Mars is like being at 100,000 feet elevation
and obviously requires a pressure suit for survival.  So Venus is super-high, and Mars is
super-low.
Clear Skies,
