Answer:- 1

The NASA scientists have characterized the first potentially habitable world outside our own solar system that may be suitable for life. The super-earth planet - named GJ 357 d - was spotted by NASA's Transiting Exoplanet Survey Satellite (TESS) mission. It is estimated that planet is about six times the size of our planet and located a mere 31 light-years away. The planet orbits a dwarf star in the Hydra constellation and may have the right conditions to support liquid water as it lies within its star's habitable zone. It may be noted that a super-Earth is an extrasolar planet with a mass higher than Earth's, but substantially below those of the Solar System's ice giants, Uranus and Neptune.
