Indian scientists discover planet 600 light years away from Earth

Indian scientists discover planet 600 light years away from Earth

The found planet is reportedly a sub-Saturn or super-Neptune-sized planet which has a radius six times that of earth, ISRO stated in its announcement on Friday. The star is located in the constellation of the Sextant, at nearly 160 light years from the sun.

The gravitational pull caused by a planet on its host star makes it wobble around their common center of mass, which can be measured using high resolution spectrographs such as the PARAS.

The team was able to identify a super-Neptune exoplanet, that is a planet bigger than Neptune also known as a sub-Saturn exoplanet.

Scientists, from the Physical Research Laboratory (PRL) at Ahmedabad have put India in the elite league of countries who have discovered planets around stars.

Launched in March 2009, Kepler is NASA's flagship spacecraft to map Earth-size planets in the Goldilocks habitable zone of other stars.

"Although the atmospheric temperature of red dwarf stars, around which these planets revolve, is 3,450 and 3,800 Kelvin respectively, nearly half the temperature of our Sun", the researchers said. The surface temperature of both stars is two times less than solar, however, the planet is exposed to intense radiation, as they are located close to bodies.

Researchers have determined that the atmospheric temperature of these two red dwarf stars approaches between 3,450 and 3,800 K which is much less than our own sun, with only half of its intensity.

Scientists of the Canary Institute of astrophysics and the University of Oviedo have discovered a planetary system where three planets earth-like type. Isro said very few such spectrographs exist around the world that allows such precise measurements. The mass and the radius of the planet help to suggest that 60%-70% of the total mass consists of ice, silicates, and iron contents.

Otherwise, the planets are probably inhospitable: they are very close to their star and therefore very warm.

Specifically, the PARAS made it possible for the scientists to measure how planet EPIC correlates to the amplitude produced when its host star responds to its orbit. And thus, the 1.2m telescope, PARAS, was put to use from the Gurushikhar Observatory in Mount Abu, Rajasthan.

The planet orbits a Sun-like star 600 light-years away.
