Astronomers have said that one of the first discovered worlds, just 31 light-years away, could contain liquid water on the surface.
The Transitation Exoplanet Survey (TESS), a high-powered orbital telescope that explores the skies for extraterrestrial worlds, has discovered three new planets orbiting the constellation Hydra, including supernatural lands that may be habitable.
The planet GJ 357 db orbits a star about 31 light-years away in what is called the habitable zone, a region far from its star so as not to be too hot but close enough to not be too cold.
In this region, it is possible to find liquid water on the surface of the planet if it turns out that the atmosphere is thick and rocky, but further research is needed to determine whether the atmosphere of the GJ 357 I am dense enough and warm enough to hold liquid water.
The news comes days after the discovery of three new planets in an astral system 73 light-years from Earth.
"The GJ 357d is located on the outskirts of the habitable star, where it receives the same amount of starry energy from its star as Mars receives from the sun," said Diana Kosakovsky of the Institute's D & # 39; Astronomy Max Planck Heidelberg.
"If the planet has a dense atmosphere, future studies will be needed to identify it, as it may contain enough heat to heat the planet and allow liquid water to surface again."
Lisa Kaltniger, a professor of astronomy at Cornell University, who published a separate article in Astrophysical Journal Letters, says the planet can house life, which can be verified with future telescopes.
The 357 day GJ gravitates every 55.7 days, about 20% of the Earth's distance from the sun.
The three planets revolve around the star known as GJ 357, a dwarf M, which is 40% colder than our sun and about a third of the mbad of its mbad.
The planet closest to the Earth, among the three recently discovered planets, is called GJ 357b, which is about 22% larger than Earth, gravitating around its star 11 times more than Mercury around the sun. .
The last middle planet is called GJ 357 c. It has a mbad of at least 3.4 times the mbad of the Earth and circulates around its star every 9.1 days.
