I was wrong to believe our earth was the only planet with ice/water. I still believe my original theory the earth came from someplace and got caught up in the suns gravity and now orbits the sun.
Is There Ice on Other Planets?
NASA's Messenger mission saw bright spots at Mercury's north and south poles. Scientists think the bright spots might actually be water ice that is deep inside craters.
Both poles on Mars have ice caps that grow and shrink with the seasons. These ice caps are made mainly of water ice. NASA's Mars Reconnaissance Orbiter took photos of the sand dunes The slopes of these dunes were covered with carbon dioxide snow and ice—what we’d call “dry ice” here on Earth.
Uranus and Neptune both contain chemicals like methane, sulfur and ammonia in their atmospheres. It’s really cold that far away from the Sun. So, these chemicals might be frozen or trapped in crystals of ice. Because of this, Uranus and Neptune are called "ice giants."
Farther out in our solar system lies the dwarf planet Pluto. And in 2016, NASA's New Horizons mission discovered a mountain chain on Pluto capped with methane snow and ice.
Our own Moon shows evidence of having water ice in deep craters near its south pole. NASA spacecraft, such as the Lunar Reconnaissance Orbiter, have found evidence of water ice.
Europa is one of Jupiter’s many moons. Scientists think that Europa has a crust of water ice that floats on a saltwater ocean covering the entire moon.
Ganymede is another icy moon of Jupiter. Ganymede is mostly made of water ice, but it also has a rocky core.
Another of Jupiter's moons, Callisto is made up mainly of rock and water ice. It may also have other ices like ammonia ice and carbon dioxide ice.
Enceladus
Saturn has more than 60 moons, all mostly made of water ice. Saturn’s moon Enceladus has a water-ice crust over a saltwater ocean.
