Yeah it makes intuitive sense that the higher mass rock balls would be more likely to hold onto their atmospheres.

Also Venus is close enough to the Sun that it gets about 1.7 times as much radiation as the Earth. That means Venus's average temperature would be about 200 C ( 390 F ) hotter than Earth even if it wasn't a runaway green house. Venus was doomed to have all it's water boil off as the Sun heated up just because its so close to the Sun.
