European astronomers have found a new exoplanet in the GJ 625, M-dwarf star, situated 21 light years away. While the other new "Super Eart" was discovered by astronomers from the Harvard-Smithsonian Center in the LHS 1140b faint dwarf star.
The closer new "Super-Earth" in GJ 625 was first detected first in 2013 by astronomers from the Canary Islands Institute of Astrophysics. The team was led by Alejandro Suarez Mascareño, who has published their finding in the arXiv repository on May 18. This new "Super Earth" is only 21 light years away from the Earth, with its mass is a little less than Neptune.
Following their three and a half years of observation, the astronomers have finally completed the study of the new "Super-Earth" orbiting the GJ 625. According to their report, they analyzed the exoplanet using the radial-velocity (RV) time series analysis. The analysis was conducted from the spectrograph of the High Accuracy Radial Velocity Planet Searcher for the Northern Hemisphere (HARPS-N) in the Telescopio Nazionale Galileo at the Roque de Los Muchachos Observatory in Canary Islands, Spain.
The other new "Super-Earth" was located on LHS 1140b faint dwarf star. This planet was discovered last month by a team of astronomers led by Jason Dittmann of the Harvard-Smithsonian Centre for Astrophysics in Massachusetts, United States. They have also published the finding in the journal Nature in Vol. 544:7650 on April 20, 2017.
The new "Super-Earth" is 40 percent larger than the Earth with an 11,000 miles diameter much more massive than our planet. It has a rocky surface that resembles the Earth. Scientists believe this planet is one of the best candidates for close observation by the new James Webb Space Telescope, which to be launched next year.
Both new "Super-Earth" exoplanets have added to the list of planets in the extra orbital region. Watch the artist impression of the exoplanet in the LHS 1140b below:
