I always wondered this question i tried to ask my teachers but i keep forgetting so DOES the gravity of a planet determines its Density?
One way to understand all this is notice what Jfizzix says here and make one simple equation out of it with everything (radius density gravity) compared with Earth as a standard:So what if a planet the size of pluto or the moon had the gravity that is 5 times that of earth? will it be higher or lower than earth density???
surface gravity compared with Earth's = G... the surface gravity would be proportional to density times radius...
