Homework Statement
calculate approximately how much more massive the Earth would have to be before it could retain a significant hydrogen atmosphere, assuming the Earth’s density to be the same as its current value.
Homework Equations
Temperature limit to retain hydrogen in the Earth's atmosphere: T «< 5042 (Mp/Rp ) *mn
Mp= ratio of mass of planet/body to Earth’s RE
Rp = ratio of radius of planet/body to Earth’s
mn= atomic mass number of gas particle
