New Delhi, June 21: The Ahmedabad-based Physical Research Laboratory (PRL) has discovered a sub-Saturn or super-Neptune size planet (with mass equivalent to 27 Earths and size six times of Earth's radius) around a Sun-like star, an official statement said on Thursday.
This discovery is very important for understanding the formation mechanism of such super-Neptune or sub-Saturn kind of planets that are too close to the host star and as well as planet formations around Sun-like stars, said the Space Department statement.
The planet will be known as EPIC 211945201b or K2-236b.
With this discovery, "India has joined a handful of countries which have discovered planets around stars beyond our solar system", it said.
The research work has appeared online in Astronomical Journal of the American Astronomical Society.
The discovery was made by a team of scientists and engineers led by Abhijit Chakraborty by measuring the mass of the planet using the indigenously designed "PRL Advance Radial-velocity Abu-sky Search" (PARAS) spectrograph integrated with 1.2m Telescope at PRL's Gurushikhar Observatory in Mount Abu, India.
"Only 23 such planetary systems (including this discovery) are known to this date with masses between 10 and 70 Earth mass and size of 4 to 8 Earth radii with such precise measurement of mass," the release said.
"Further, PARAS is the first of its kind spectrograph in Asia which can measure the mass of a planet going around a star. Very few spectrographs exist around the world that can do such precise measurements."

Kozhikode: There are strong indications that Nimisha Priya’s death sentence in Yemen may be revoked following significant progress in recent mediation talks. According to mediators, the family of the deceased Yemeni national Talal, who was killed, has agreed in principle to pardon Nimisha.
A press release from the office of Kanthapuram A.P. Aboobacker Musliyar stated that some crucial decisions have been taken in the case. The developments follow high-level negotiations involving a delegation of Yemeni scholars appointed by Habib Umar bin Hafiz, a prominent scholar from Tarim, along with officials from northern Yemen and international diplomatic representatives.
Further discussions with Talal’s family are expected to finalise the terms, especially concerning compensation and legal formalities.
It may be recalled that Nimisha was scheduled to be executed on July 16. However, following the intervention of Kanthapuram A.P. Aboobacker Musliyar, the execution was temporarily postponed on July 15.
