One sign that a moon is really a captured asteroid is that it has a nonspherical shape, or looks more like a potato than round like our moon. As the central body, or protostar, of the system contracts and heats up, the increasing pressure of its radiation is believed to drive off much of the thinner material of the protoplanets, particularly those closer to the nascent star.
