The image of the new object was taken in May and August in the early of testing the planet hunter's Subaru telescope located in Hawaii.
Objects called GJ 758 B is orbiting a parent star that have mass and temperature comparable to our sun. The star is 480 trillion km, or about 50 light years from Earth.
Scientists are not sure whether the object was a large planet or a brown dwarf (brown dwarfs), or also known as a failed star. The mass of the object was estimated to 10-40 Jupiter size. Objects that have mass above 13 of Jupiter (and still below the mass necessary to trigger a nuclear reaction on a star) is considered as brown dwarfs.
After all, McElwain admitted that the pictures were quite interesting. "Brown dwarf star like our sun with extremely rare. Interesting discovery was something so cold and so low mass near that of a star so similar to our solar system."
The distance similar object like planet from the star is at least 29 times the distance of Earth to the Sun, or roughly the distance between the Sun to Neptune. Astronomers believe that most of the major planets formed at distances closer or farther from the star, but not at a distance where the GJ 758 B is now located.
