Indian scientists discovered a planet 600 light years away, the planet is a sub-Saturn or super-Neptune size planet, which is about 27 times the mass of Earth and six times the radius of Earth.
A team of scientists from the Physical Research Laboratory (PRL), Ahmedabad, have discovered the planet. The planet revolves around a sun-like star. ISRO on their website posted the name of the host star as EPIC 211945201 or K2-236 and the planet will be known as EPIC 211945201b or K2-236b. The planet was found to go around the star in about 19.5 days.
The discovery was made by measuring the mass of the planet using ‘PRL Advance Radial-velocity Abu-Sky Search’ (PARAS) spectrograph integrated with 1.2m telescope at PRL’s Gurushikar Observatory in Mount Abu. The temperature on the planet is said to be 600-degree Celsius. The planet is said to be uninhabitable.
The discovery became important as it helps to understand the formations of Neptune and Saturn-like planets. Times of India reported that the planet goes around the star and hence blocks a little star-light. By measuring the amount of light blocked by the planet body, the diameter or size of the planet can be measured. This detection was important as it adds to a sparse catalog of confirmed exoplanets with masses between 10 and 70 MEarth and radii between 4 and 8 REarth, whose masses and radii are measured to a precision of 50% or better.
Including this, there are only about 23 such systems known to the scientists with precise measurements.
