There are lots of reasons to make merry for the discovery of new exoplanet – GJ 1132b. Though the discovery of exoplanets is not something, new GJ 1132b is exceptional from all other exoplanets as it has its own atmosphere, just like our own planet Earth has. A team of international scientists, in their recent breakthrough, has stumbled upon a new Earth-sized planet, orbiting outside the solar system and surprisingly it has its own atmosphere. It is a first-of-its-kind discovery of a low-mass rocky planet, which can provide researchers new insights into the fuzzy concept of the perspective for life on outer worlds.
The study paper, published in The Astronomical Journal has mentioned about the discovery of the new exoplanet – GJ 1132b, which is located only 39 light-years away from Earth. The breakthrough is believed to be a significant advancement towards the unearthing of possible alien lives on other planets. The recognition of an environment around Earth-like GJ 1132b marks for the first time detection of an atmosphere outside the solar system.
In terms of measurement, the new exoplanet’s mass and the radius are quite close to the Earth’s mass and radius which is 1.6 Earth masses, 1.4 Earth radius, said researchers from University of Cambridge and the Max Planck Institute for Astronomy, who mutually conducted the study. As highlighted by the researchers, the new planet is 1.4 times more than the diameter of Earth and 1.6 times more than its mass. It is spotted located outside of the solar system, some 39 light-years or 12 parsecs away from Earth and orbiting around a red dwarf star.
Whereas the host star of the planet is found to be relatively cool at 3000 degrees – almost half the hotness of the sun, the planet orbits only 2.3 million kilometres away, and thus its temperature is documented as steamy 370 degrees. As said by the founder of the exoplanet, GJ 1132b is a transiting celestial object. From the viewpoint of the Earth, it crosses directly facing its host star in every 1.6 days, resulting in the blockage of some of the starlight. From the division of starlight, hindered by the planet, astronomers usually conclude the size of the planet, and in this case, GJ 1132b is estimated to be nearly 1.4 times more than the scale of the Earth.
