TOI-1452 b is located about 100 light-years from Earth and orbits one of two small red dwarf stars in the constellation Draco.

Researchers believe it could be an “ocean planet,” meaning a planet completely covered by a thick layer of water. They compare it to Jupiter’s moons Ganymede and Callisto, and Saturn’s moons Titan and Enceladus, which have subterranean oceans.

The outer planet TOI-1452 b is stated to be about 70% larger than Earth. The researchers needed more than 50 hours of observations to estimate the mass of the planet, which is almost five times the mass of Earth. Scientists believe that the new exoplanet is rocky like Earth, but the water in TOI-1452 b can make up 30% of the mass of the planet, while on Earth – 1% of the mass.

“TOI-1452 b is one of the best ‘ocean planet’ candidates we’ve found to date. Its radius and mass indicate a much lower density than would be expected for a planet like Earth that is mostly metal and rock,” said researcher Charles Cadeau.

As reported by Ukrinform, a group of astronomers under the scientific leadership of the University of Hawaii at Manoa (USA) took a direct photo of 2M0437b, one of the youngest exoplanets ever found outside the Solar System.
