Is it possible for a Rocky Giant with rings around it?

  1. Apr 8, 2005 #1
    Most giant planets we know of are Gas Giants. Is it possible for a planet made of rocks to be the size of jupiter? In other words is it possible for a Rock Giant?

    Also, is it also possible for a rocky planet to have rings around it like Saturn? Though we have found no rocky planet with rings around it, it is still very possible because those rings aren't linked to the gas of a Gas Giant, right?

    Right. It's possible that the Earth had a ring system when the moon was first forming.

    The problem is that such a planet will hold on to any gases escaping from its interior very well. As a result, it will most likely end up with a thick dense atmoshere. IOW, it will take on the appearance of a gas giant with a rocky core.

    Could Jupiter or any other gas giant have a rocky core?

    Also, have we found other giant planets in other solar systems yet that appear to be giant but instead of it being a gas planet it actually appears as a rocky planet?
