Discover the first two large planets equal to the earth outside the solar system

NASA's Kepler Space Telescope discovered the first two large Earth-like planets, orbiting a star like the sun outside the solar system. This is an important milestone in the search for earth-like planets.

The planets are called Kepler-20e and Kepler-20f . These are the smallest planets outside the solar system, confirmed to revolve around a star that resembles our sun, NASA claims.

These planets are too close to their host star, so it is not in the region where there is supposed to be life, where liquid water can exist on the surface.

'The discovery for the first time shows that planets the size of the earth exist around other stars and we can detect them,' said Francois Fressin, of the Harvard-Smithsonian Center for Astrophysics. in Cambridge, Massachusetts, USA, said.

The new planets are thought to be made of stone. Kepler-20e is slightly smaller than Venus, has a radius of 0.87 times the radius of the earth.

While Kepler-20f is slightly larger than the earth, the radius is 1.03 times that of the earth. Both planets are in the five planetary system called Kepler-20, in the constellation Lyra, about 1,000 light-years from Earth.

Kepler-20e's orbit around the master star is 6.1 days while Kepler-20f is 19.6 days. The surface temperature of Kepler-20e is about 1,400 degrees Fahrenheit, which can cause the glass to melt.
