In order to discover the new celestial body, scientists used combined methods of transit
The planet they discovered is called Gliese 486b, and it has 2.8 times the mass of Earth and is 30% more voluminous than our planet.The composition of the planet is similar to Venus or Earth if they had metal cores.
Gliese 486b revolves around the host starevery 1.5 days at a distance of 2.5 million km. Despite the fact that the planet is so close to its star, it, according to the authors, has retained some of its original atmosphere. Therefore, the authors plan to continue observing it using the next generation of space and ground-based telescopes.
The diagram gives an estimate of the internal composition of individual exoplanets based on their masses and radii in terrestrial units.The red dot is Gliese 486b, and the orange dots are planet planets around cool stars like Gliese 486.
Gliese 486b rotates on its axis for as long as it does around its host star, so it always hasthe same side that faces the star.
Although Gliese 486 is much weaker and colder than the Sun,its radiation is so intense that the planet's surface heats up to 430 degrees Celsius. Because of this, the surface of Gliese 486b is likely more like the surface of Venus than the surface of the Earth. It is a hot and dry landscape with burning lava rivers. However, unlike Venus, Gliese 486b may have a thin atmosphere.
