Objects whose size is five times larger than Jupiter it could be the cause of mass extinction that occurred 26 million years ago.
Stars who have nicknamed Nemesis by NASA scientists, can not be seen even remove infrared light and very far away.
Nemesis is believed to orbit the solar system at position 25 thousand times the distance between the Earth to the Sun.
Along with the rotation of the galaxy, the force of gravity pulling out its ice bodies from the Oort cloud, a very broad layer consisting of rocks and dust as far as Nemesis.
Fireball flying into the earth is shaped comet caused total damage when sweeping out the dinosaurs 65 million years ago.
Currently NASA scientists believe they will be able to find Nemesis using heat-seeking telescope that will begin to scan the sky in January.
The tool is called Wide-Field Infrared Survey Explorer is expected to help find thousands of dwarf stars within 25 light years from the Sun, which sends back images that may be released from the comet swarm Oort cloud.
Scientists first clue to the existence of Nemesis is a strange orbit of the dwarf star called Sedna. The researchers looked at the morbidity, oval orbit within 12 thousand years can be explained by the structure of the massive sky.
Mike Brown, who discovered Sedna in 2003 said, "Sedna is a very peculiar object, the object is not supposed to be there. The only way to obtain an eccentric orbit is to have a giant structure that supports it, so what's going on out there
