Apart from Earth, there are 10 such moons and asteroids present in the Solar System, where Oceans are present.

Looking at the seas and oceans present on our earth, it seems that this is only on our planet. However, not only does the ocean exist on Earth, but they also have presence on many moons and asteroids present in our solar system. In such a situation, let us know about 10 such oceans present in the solar system.
2/11
Europa: There is evidence of the presence of water on Europa, the fourth largest moon of Jupiter. NASA’s Hubble telescope saw steam rising up to 200 km above its south pole. This suggests that a layer of ice is present on Europa, which may be just a few kilometers thick. Apart from this, there can be a saltwater ocean here.

Ganymede: Jupiter’s largest moon Ganymede is eight percent larger than the planet Mercury, but its mass is only half. This can cause the presence of stone and water on this moon. Galileo Spacecraft discovered in 1990 that Ganymede had its own magnetic field, which would mean its core was molten iron. The heat emanating from this core will be sufficient to melt the ice and create a vast underground ocean. This ocean can be 100 km deep between the two icy layers.
4/11
Callisto: Jupiter is the second largest moon of the planet Callisto, which is almost as large as Mercury. But one third of it is huge, which means that about 50 percent water is present here. When the Galileo spacecraft measured its gravity, it was found that its internal structure was not completely separated from the stone core with an ice cover. Because of this, the ice has never melted.
5/11
Pluto: Pluto is so small that it cannot retain enough heat to melt its core. But there is so much heat on it that it can melt the light element. Due to this, its 1700 km rocky area is surrounded by water and ice. This gives evidence of being an ocean here.
6/11
Ceres: Ceres is the largest object in the asteroid belt and the only dwarf planet in the inner solar system. It is basically made up of a mixture of rocks with about 10 percent ice. The ice present here melted due to radioactive activity, but it could not melt all the ice present on the surface. However, it did create an underground ocean. Because of this, an ocean of ice exists beneath the surface of Ceres.
7/11
Triton: Triton is the largest moon in Neptune. When the first information about it was received, its initial orbit was very strange. This produced a lot of tidal heat. This heat was enough to melt its interior. This melted the ice present here and separated it from the ice core. When this happened, the melted ice became a sea.
8/11
Mimas: Saturn’s moon Mimas can be made up mostly of water ice which also contains a piece of rock. In a recent research, it has been told that there is an ocean in its bottom, which is covered by a very thin layer.
9/11
Enceladus: In 2005 NASA’s Cassini spacecraft saw steam emitting near the south pole of Enceladus, the moon of Saturn. There is a rocky core on the Enceladus for a distance of about 370 km, surrounded by an ocean 10 km deep under the icy crust.
10/11
Dion: Saturn’s moon Dion with a heavy rock core may have 50 percent water. Because of this, there is a crust of frozen ice here. NASA says the crust is swimming 35–95 km deep.
11/11
Titan: Apart from Earth, the only Titan in the Solar System is the place where there is enough atmosphere and surface fluids. The temperature on Titan is -180 ° C, due to which water cannot remain in liquid state. But this liquid is perfect for methane and ethane. They both evaporate in the atmosphere and then fall down in the form of rain, which makes rivers, lakes and oceans.
