A research team has discovered an exoplanet about 100 light-years from Earth in the constellation Draco , and they say it looks like Earth is covered by a deep ocean .

The exoplanet, designated TOI-1452b , is located in a “Goldilocks region” that is slightly larger than Earth and where temperatures are neither too hot nor too cold for liquid water to exist. Therefore, astronomers think TOI-1452b may be covered by an ocean.

The exoplanet orbits a “nearby visual-binary M dwarf” star. University of Montreal researcher Dr. Charles Cadieux led the international team in the discovery, and their research has been published in the Astronomical Journal.

The Planet Has Rocks Like It Does On Earth

According to Phys.org, Cadieux describes the new exoplanet they discovered:

“TOI-1452b is one of the best candidates for an oceanic planet we’ve ever found. Its radius and mass indicate a much lower density than would be expected for a planet like Earth that is mainly composed of metal and rock.”

The exoplanet orbits a star much smaller than our Sun and likely has rocks like Earth, but with a very different mass, radius and density, the researchers said. They say more will be learned about TOI-1452b as NASA’s new James Webb Telescope begins its atmospheric characterization efforts.
