GSC 03549-02811 A (referred to as TrES-2 or TrES-2 A in reference to its exoplanet) is a yellow main-sequence star similar to our Sun. This star is located approximately 718 light-years away in the constellation of Draco. The apparent magnitude of this star is 11.41, which means it is not visible to the naked eye but can be seen with a medium-sized amateur telescope on a clear dark night. The age of this star is about 5 billion years.〔(【引用サイトリンク】 title =SIMBAD query result: NAME TrES-2 Parent Star -- Star )〕 ==Planetary system== In 2006 the exoplanet TrES-2b was discovered by the TrES program using the transit method. It is also within the field of view of the previously operational Kepler Mission planet-hunter spacecraft. This system continues to be studied by other projects and the parameters are continuously improved. The planet orbits the primary star.〔 Though TrES-2b is currently the darkest known exoplanet, reflecting less than 1 percent of local sunlight, it does show a faint red glow. It is assumed to be tidally locked to its parent star.〔http://news.yahoo.com/coal-black-alien-planet-darkest-ever-seen-220601419.html〕
