The US space agency NASA has found an icy twin of our planet which has same mass and distance that Earth revolves around the Sun. The scientist said that the chances of life sign are very less as this is too cold. It is said to be even colder than the Pluto.

This new planet revolves around a star which is very tiny in compare to the sun. The mass of its star is just 7.8% of our sun. So, astronomers really suspect it to be a star. This new planet which is 13,000 light years away named as ‘OGLE-2016-BLG-1195Lb’ by NASA.

Scientists have the different view on this star, some of them say that it could be the brown dwarf. It is kind of star-like object which is not able to produce energy via nuclear fusion from its core.

On the other hand, they call it ultra –cool dwarf which is like TRAPPIST-1.  This is recently discovered by Spitzer and ground-based telescope which is hosting seven Earth-size planets.

This new planet was beyond the reach; however, microlensing techniques have made it possible to detect. This method provides the capability to scientists to discover the most distant stars which are thousands of lights years away.

Yossi Shartzvald, the main author of the study, said that this planet, which he call it ‘Iceball’, is the lowest-mass planet ever detected by microlensing.

As per NASA officials, this new planet will help to find out the distribution of planets in the space.

Geoff Brydon, the co-author of the study said that we have a few number of planetary systems which are this far outside our solar system. Due to the absence of Spitzer detections in the bulge tells that planets may be less common towards the center of our solar system rather than on the disk.

What is microlensing technique?

This method basically provides the ability to discover the distant objects /stars by using background stars as flashlights. So, whenever a star passes in front a bright star in the background, the gravity of foreground star makes it brighter. Hence, an object revolving around the foreground star may cause the extra blip in the star’s brightness. However, in this case, this blip remain visible for a few hours.

This method is helpful in detecting the low mass objects which are very far from their stars. This can even detect the star which is farther than the Earth is from our sun.
