rigney Posted March 20, 2012 Share Posted March 20, 2012 (edited) I was trying to follow a post about gravity and magnetism that was just too technical for me and wondered if someone might have an idea about this question. How can an almost non-ferris asteroid such as Ida have a moon? It's must be either one of two things, gravity or magnetism. Considering where the asteroid belt is located and the complexity of its formation, it strains my mind that it can even exist. Took this link from the net.
