Earth-sized Planets Discovered in Planetary System

  • Indian scientists discover planet 600 light years away from Earth

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.

The Indian Space Research Organisation (ISRO) has a detailed report on how the scientists made the breakthrough.

The planets, which were discovered around a star called K2-239, are incredibly close to Earth in overall size, with radii measuring between 1.0 and 1.1 times that of our own planet. It is closer to Neptune, he added.

The first exoplanetary system is located about 160 light years from Earth.

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.


With this discovery, India is now among the league of countries that have discovered planets around stars.

In the journey for finding more Earth-like planets, scientists from the "Instituto de Astrofísica de Canarias" (IAC) and the University of Oviedo in Spain have gathered data collected by the Kepler telescope on a red dwarf star, dubbed as K2-239. Since the planet revolves around host star EPIC 211945201 or K2-236, it will be known as EPIC 211945201b or K2-236b - ISRO said.

NASA's Kepler satellite, which was launched in 2009 as part of the K2 mission, has uncovered three Earth-sized planets in another solar system. The mass and the radius of the planet help to suggest that 60%-70% of the total mass consists of ice, silicates, and iron contents. This is the first of its kind spectrograph in the country, which can measure the mass of a planet going around a star. "Very few such spectrographs exist around the world (mostly in the US and in Europe) that can do such precise measurements", the official statement said. This is what they have so far discovered. The scientists have used a PARAS spectrograph for calculating the mass of the planet.

The planets are a close match to Earth in size, but they're positioned much, much closer to their star than Earth is to the Sun.

Though unique in its own way, this "epic" planet is one of 22 other confirmed exoplanet systems with the same dimensions.
