Scientists 'discover new exoplanet Rosetta Stone' while searching alien world

Astronomers have discovered a new alien world that would help m understand atmosphere of rocky planets. In study published in Journal Science, a team of astronomers from Max Planck Institute for Astronomy have announced discovery of a nearby exoplanet that could be an ideal target for search for habitability. newly discovered exoplanet Gliese 486 b, circles a dim red dwarf star just 26 light-years from Earth and is about 1.3 times larger and 2.8 times more massive than Earth, study reports. 

Exoplanet which could be 'Rosetta Stone'

Trifon Trifonov, a planetary scientist and le author of study examined about 350 red dwarf stars to find signs of planets orbiting m. According to study, Red dwarfs are small stars that are most common in universe. In process, team of scientists discovered a "rocky super-Earth that's right in our cosmic neighbourhood". " exoplanet must have right physical and orbital configuration to be suitable for atmospheric investigation," said planetary scientist Trifon Trifonov in research published in Journal. Trifon Trifonov told Space.com that combination "of physical and orbital characteristics of Gliese 486 b makes it 'Rosetta Stone' for atmospheric investigations of rocky exoplanets".

Gliese 486b orbits its host star on a circular path every 1.5 days, at a distance of 2.5 million kilometres. Despite being so near to its star, planet has probably conserved part of its original atmosphere. Trifon Trifonov in study has said that fact that this planet is so near sun is exciting because it will be possible to study it in more detail using powerful telescopes such as imminent James Webb Space Telescope and Extremely Large Telescope which is now being built.” surface temperature of exoplanet, however, is closer to that of Venus, so Gliese 486 b is not a great candidate for life as we know it, said Trifonov, who envisions a world that's "hot and dry, interspersed with volcanos and glowing lava rivers."
