Planet 600 Light Years Away From Earth Discovered by Indian Scientists

That looks for the brief dips of light that happen when a planet passes in front of its star, and allows scientists to use the details of those dips to work out what they might be like. It is located in the constellation of the Sextant at 50 parsecs from the Sun (at about 160 light years).

The discovery was made by the astronomy team headed by Professor Abhijit Chakraborty of PRL. "It's closer to Neptune", he said. It is seven times closer to the star as compared to the distance between the Earth and the Sun.

The gravitational pull caused by a planet on its host star makes it wobble around their common center of mass, which shifts the spectra and can be measured in terms of Radial Velocity using precise and stabilised High Resolution Spectrographs, like 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. The total mass of these elements was calculated at about 60 to 70 percent of planet EPIC's total mass. It has the name EPIC 211945201 (K2-236) and thus, the planet has been given the name EPIC 211945201B (K2-236B).

Another red dwarf - K2-240 - there are two super-earths, in each of which the diameter exceeds the Earth twice.

The PARAS is the first spectrograph of its kind in India.

"The spectrograph is the first of its kind in the country which can measure the mass of a planet going around a star". Isro said very few such spectrographs exist around the world (mostly in the United States and Europe) that can do such precise measurements. They will also determine masses, densities and other physical properties of the planets that have found by using the ESPRESSO instrument (which is installed in the Very Large Telescope) at the European Southern Observatory (ESO). The report said it was Nasa's K2 (Kepler2) photometry that found that the source was a planetary candidate as it was transiting, where the planet body comes between the star and the Earth. This planet revolves around a Sun-like start in its solar system. It's very hard to discover an exoplanet because they are usually billions of times fainter than the stars they orbit.
