According to a study published in The Astronomical Journal, astronomers report the discovery of an exoplanet, TOI-1452 b, about five times the mass of Earth, 30 percent of which is water, orbiting a distance of One of a small binary star system in the constellation Draco, about 100 light-years away from Earth, may be an “ocean planet” completely covered in water. Analysis suggests that TOI-1452 b may be a rocky planet like Earth, but its radius, mass and density data show it is very different from Earth. Earth is inherently a very dry planet, and although it is sometimes called the blue planet because about 70 percent of its surface is covered by oceans, water actually makes up less than 1 percent of Earth’s mass. The water of TOI-1452 b may account for 30% of its mass, which is similar to some natural satellites in the solar system, such as Ganymede, Callisto, Titan, and Enceladus, and may be an “ocean” planet”, a planet completely covered by a thick layer of water.
