They range from.0.69 grams per cubic centimentrs for Saturn (which would float if you had a big enough container of water) to 1.63 for Neptune, 3.35 for Mars, to Earth at 5.51 despite the layer of water. Second the stuff at the bottom of the ocean is sort of a premined resource with nodules of manganese and other high concentration metals over large areas. Diamonds have washed into the ocean from African rivers... We know there have been many reports of Unidentified Submerged Objects, Earth would be a much better location than an asteroid for camping, etc. I guess that basically I am assuming that every advanced technological civilization is concerned about its security and must keep tabs on the primitives in the neighborhood especially those who like us, show signs of being able to bother them..
