Discover the nearby neighborhood of the solar system

An American astronomer said he had found a pair of new stars lying close to the solar system, and also the nearest neighbor to be discovered since 1917.

Astronomers of astronomy and astronomy, Professor Kevin Luhman of Pennsylvania State University in the US said they found the nearest neighbors of the sun.

The pair has been discovered thanks to a celestial survey conducted by the WISE satellite of the US Space and Aeronautics Agency (NASA), confirmed by terrestrial telescopes, according to Space.com.

Accordingly, they are in the form of brown dwarfs, indicating stars that are too small in mass to be hot enough to burn hydrogen.

Such stars are cold and faint, like giant Jupiter-like planets rather than shining like the sun.

'The distance to this brown dwarf is about 6.5 light-years away, so close that the TV signal emitted from Earth in 2006 has reached that place,' Professor Luhman said in a press release. of the above university.

The new star system, called WISE 1049-5319 , is just a bit further than the second nearest star Barnard star, 6 light-years from the sun, discovered in 1916.

Thus, the nearest solar system includes Alpha Centauri, discovered in 1839, 4.4 light-years from the sun, and Proxima Centauri in 1917; 4.2 light years away.
