Hi,
some people say that pressure in the space is zero because there is nothing in space and some say that, it would be 10^-12 torr because of presence of some hydrogen between the planets anyhow if it is 0 or 10^-12 torr infact it is very low pressure so
Why not space suck the gases from planets?

Hi Uzair:
I posed your question to " an expert on the subject" and here's your answer:
The gravity from planets is directly proportional to their mass
(mass x gravity = weight).
A massive planet has far more mass than the nearly empty interplanetary (interstellar) medium. So the space between planets hasn't enough mass to cause any appreciable attraction to "steal" the planet's upper atmospheric gases.
However, a few gas atoms do escape from the planet's upper atmosphere due their own high velocity , but on average a planet's atmosphere stays intact.
Wishing you well.
