Don't forget, velocity of the molecules also depends on temperature.  So a
*cold* small world can hold stuff that a small world in Earth's orbit
couldn't.  Of course, that may not work with the planets Brad is posting,
since he isn't describing them as really cold.  Also, too cold and you end
up with lots of gases condensing out.  :P
