What Are Exoplanets ?Planets outside of our soar system are called exoplanets . Most of these are part of Star System . There are some "rogue " exoplanets , which are not attached to any star system.
When Was First Exoplanet Discovered ?
The first exoplanet 51 Pegasi b was discovered in 1995 by Michael Mayor and Didier Quetoz.
Highlights :-◆ A team of scientists from the Physical Research Laboratory ( PRL ) , Ahemdabad discovered a Sub - Saturn or Super Naptune size exoplanet which is about 27 times the mass of earth and six times the radius of earth .
◆ The planet revolve around a Sun - Like star , around 600 light years away from earth.
Name Of The Host Star :-EPIC 211945201 or K2-236 and the planet will be known as EPIC 211945201 b or K2-236 b.
Discoverey Of Exoplanet :-The surface temperature of planet was found to be around 600 ℃ , as it is very close to to host star in comparison with earth - sun distance . This might make it uninhabitable.
Importance :-◆ This detection was important , as it adds to a spare catalogue of confirmed exoplanets with masses between 10 and 70 M earth and radii between 428 R earth , whose masses and radii are measured to a precision of 50% or better.
◆ Only 23 such systems are known to this date with such precise measurement M and R.
Physical Research Laboratory :-The Physical Research Laboratory ( PRL ) is a National Research Institution of space and allied sciences , supported mainly by development of Government of India , known as the cradle of space sciences in India , the PRL was founded on 11 November 1947 by Dr. Vikram Sarabhai.
Mount Abu Observatory :-Mount Abu Observatory ( MAO ) is an important part of PRL . It is located near the town Mount Abu , in the state of Rajasthan. The observatory is at altitudes of 1680 meters and is adjacent to Guru Shikhar , highest peak of the Aravali Range .
Mount Abu has about 200 cloud free nights of which nights a year can be used for photometric observations.
