Hi, I'm new to this and trying to explain gravity to a 10 year old ! My question is.. If I was floating in space on directly the opposite side of the sun to earth, in the same orbit as earth...would earth eventually catch me up ? if not (as I thought everything in the same orbit moves at the same velocity), how would a planet clear its orbit..... I read somewhere about the 'perception' of gravity being that it pulls you down, but if you were an observer in space you'd see it was the earth accelerating into you..so trying to figure out whether I understood that correctly... thanks, Ant.
