The total mass of this planet's atmosphere may be higher than the Earth's but the gases present must be very light ones like hydrogen and helium.
The escape velocity of the planet will be very high.
Due to the high escape velocity, the light gases were not able to escape and hence forming a thick atmosphere
Is the escaping velocity for this planet greater or lower than that of the earth?
What would Earth's surface gravity and escape speed be if
the entire planet had a density equal to that of the crust (3000
kg/m³, say)?
