Why if we put Saturn in water, it will float?

    Density is 0.7. Anything less than 1 floats. (Where do expect to find a big enough basin?

    It's a highly misleading claim, since you couldn't really float Saturn in a vessel of water of any size. (Saturn's gravitation will have deleterious effects on your vessel of water). But it is true that Saturn is less dense than water:

    Saturn masses 5.7 x 1026 kg.
    A volume of water the size of Saturn would mass 8.3 x 1026kg.
