Is there water on other planets?

There is, though in most cases where water exists on other planets it does not exist predominantly in the liquid form (like here on Earth). On some planets there may be trace amounts of water vapor in the atmosphere, beds of ice on a planet’s surface, or superheated, ionized water near a planet’s core. There may well be other planets out there with liquid water, but humans have not found many with large amounts of liquid water.
