Nearby Exoplanet Might be Habitable for Humans – Says NASA

Science

NASA’s Transiting Exoplanet Survey Satellite or TESS has found some extraordinary exoplanets. Recently, the satellite found an Exoplanet which has three red dwarf stars. That was a shocking and exciting revelation as this is the first time we’ve spotted a planet with three stars and it revolves around the primary star. But now, NASA said that the TESS found a new exoplanet, which might be habitable for humans. A group of astronomers has discovered an Earth-like planet which revolves around GJ 357 star in the Hydra constellation. The exoplanet is nearly 31-light-years away from our planet.

The exoplanet is named as GJ 357D is nearly 32-light-years away. One light-year is equal to six trillion miles as it nothing but the distance a ray of light travels in a year. Being that far, we humans can reach the planet in 31 years if we travel with the speed of light. According to Diana Kossakowski, who is the co-author of the paper published in the exoplanet study, says that the planet lies in the habitable zone of the star. Just like our earth, the GJ 357D is orbiting the star from the right distance.

The astronomers are expecting the atmosphere of this planet to be dense. Future studies will explain if the atmosphere is thick or not. If it is, then the planet can trap enough heat and store liquid water on the surface and also create the weather cycle. If the liquid water and enough heat are present on the planet, then it is habitable for humans in the near future. This is the first time astronomers have found the exoplanet that might be suitable for inhabiting humans. This was not possible without the help of Transiting Exoplanet Survey Satellite, said co-author of this study, Lisa Kaltenegger in a separate statement.
