Do liquid planets exist?
It is probably not possible for a planet to be entirely liquid. This is because a planet needs to be ‘self-gravitating’ so that it holds its spherical shape under gravity. However, it is possible for a planet to be entirely covered by liquid over a solid core.
What planet is 70\% liquid water?
planet Earth

Do planets like Earth exist?

The thousands of exoplanetary star systems discovered so far are profoundly different from the Solar System, supporting the Rare Earth Hypothesis.
Do asteroids have gold in them?
