HD 192263 is an 8th magnitude star about 63 light years away〔 in the constellation of Aquila. The spectral type of the star is K2V, meaning that it is an orange dwarf, a type of star somewhat cooler and less luminous than our Sun. It is not visible to the unaided eye, but with good binoculars or small telescope it should be easy to spot. Various companions for the star have been reported, but all of them are probably line-of-sight optical components or just spurious observations. The apparent direction of the star lies close to the Earth's Celestial equator, and it rotates almost edge-on to our line of sight.〔 In 1999 an extrasolar planet was announced orbiting the star. ==Planetary system== On 28 September 1999, a planet around HD 192263 was found by the Geneva Extrasolar Planet Search team using the CORALIE spectrograph on the 1.2m Euler Swiss Telescope at La Silla Observatory,〔 discovered independently by Marcy ''et al.''〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「HD 192263」の詳細全文を読む スポンサード リンク
