Thanks! But darn it, I'm going to have to figure something out! I need this planet to have standard mass and gravity. (though the thought of a Styrofoam planet is amusing.)
I don't really want to Sci Fi this. I'm going to be bending just about every other rule into a pretzel for this...
How would a solar system need to be set up to provide a life bearing world, standard 1 g, with the surface area of Jupiter with a standard day / night 24 hour cycle?
