The research team has stated that there are a number of exoplanet, a planet outside the Solar System, which has oceans up to thousands of kilometers deep. The exoplanet belongs to the sub-Neptune category, or which has a size 2-4 times larger than this Blue Planet.
It was research some time ago led by Li Zeng, an astronomer from Harvard University, that gave rise to this theory. The report itself has been published in the journal Proceedings of the National Academy of Sciences (PNAS).
“Unexpected. Bottomless. Very deep,” said Li Zeng in describing the depths of the sea in sub-Neptune, as detikINET quote from Futurism.

Thousands of kilometers is certainly very deep for a seabed when compared to on Earth. The deepest point on the planet itself is the Challenger Deep in the Mariana Trench. He is as far as 10,994 meters or less than 11 kilometers, from sea level.
In addition, this study also claims that 25%-50% of the mass of exoplanet-The exoplanet is water. It was also a very large percentage when compared to Earth.
Although about 70% of the Earth’s surface is covered with water, only 0.02% of the planet’s mass is water. Iron (32%), oxygen (32%), magnesium (15%), and silicon (15%) are the elements that make up the largest percentage of Earth’s mass.
Furthermore, if 50% of the mass of the sub-Neptunes was water, then the pressure there would be enormous. This makes most of the water there will be solid, aka ice.
The research itself uses a computer model that uses data from NASA’s Kepler space telescope. In addition, they also used data from the Gaia space telescope owned by ESA, the European space agency.
