Europa is the moon of Jupiter and has very big watery ocean lies beneath the icy outer crust. Let's know how much water is there on Europa as compared to 🌍 's water.
Europa is four times smaller than Earth. if you could form a giant sphere with all of the water on Europa, that sphere would be about 1,090 miles across - 300 miles wider than if you did the same thing with all of the water on Earth.
That's a lot of water for such a tiny moon, and it makes for a very deep and vast potential habitat for alien life.
So how deep the ocean on Europa? Scientists estimate that some parts of Europa's ocean could reach over 100 miles beneath the thick outer surface. That's 16 times deeper than the deepest place on Earth, at the bottom of the Mariana Trench in the western Pacific.
