Why is liquid so rare in your solar system?
Well, in my solar system liquid isn't really that rare. The second planet in my solar system has an almost entirely liquid crust, and a liquid mantle. The third planet orbiting the star in my solar system has a surface over 75% covered in liquid, and has a liquid mantle. The sixth and seventh planets in my solar system both have large hydrogen oceans. Several of the moons orbiting the sixth and seventh planets in my solar system also have liquids. I don't see why liquid could be called rare in my solar system. What about yours?
