Stellar object

 * The authors do not believe the new object is part of the Alpha Centuari system, however, because if it were that far away, such a star would have been bright enough to be seen before. Rather, they offer several explanations for the object, which one of the research teams named Gna. Perhaps most notably, they suggest a "Super Earth" at a distance of about 300 astronomical units (AU) from the Sun, or about six times further than Pluto is at its aphelion. Another explanation is a "super-cool" brown dwarf (too big to be a planet, too small to be a star) at about 20,000 AU from the Sun.
