Planet 600 Light Years Away From Earth Discovered by Indian Scientists

Scientists Discover New Planet'EPIC 211945201 600 Light Years Away at Mount Abu Observatory

Exoplanet

The Physical Research Laboratory is a unit of Department of Space that carries out research in areas of physics, space and atmospheric sciences, astronomy, and planetary and geo-sciences.

Ahmedabad have discovered a sub-Saturn or super-Neptune size exoplanet. The newfound planet revolves around a Sun-like star which is some 600 light years away from Earth, reported The Times of India.

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.

Researchers at the PRL believes that the discovery of such planets will help them to study the formation of sub-Neptune or sub-Saturn like planets.

With this discovery, India is now among the league of countries that have discovered planets around stars. K2-239 has a compact system, and three of its planets have a similar size to Earth, which orbit that star once every 7.8 and 10.1 days.

"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.

Was it really "socialist"? "They're also anxious about the retaliatory measures that we will take". I suspect the personal will also be more fascinating than the political in Singapore this week.

The PARAS is the first spectrograph of its kind in India. The scientists have named the planet EPIC211945201b or K-2 236b.

On the other hand, only a few such accurate and powerful spectrographs exist around the world, the majority of which being in the USA and Europe.

Based on the mass and radius, model-dependent calculations suggest that the heavy elements, like ice, silicates, and iron content is 60 to 70% of the total mass. It can measure the mass of a planet revolving around its star.

Scientists now hope to use further observations - from the new James Webb Space Telescope - to understand more about the planets' atmospheres. As this system is reported to feature three rocky planets that are the same size as Earth, astronomers are taking notice.

In a discovery by NASA, it was said that the NASA's Kepler satellite has discovered three Earth-like planets has been found.

Since it closely rotates around a hot star, the planet bears a temperature of around 600 degree centigrade.
