It was first identified by John Herschel in 1831.〔 The two stars are separated by 1500 AUs. The star system is estimated to be 3.6 billion years old.〔 The secondary star ADS 16402 B is also designated HAT-P-1. == Planetary system == In 2006 the HATNet Project announced the discovery of a hot jupiter type gas giant extrasolar planet in orbit around the secondary star. Following the designation scheme used by the HATNet Project, the secondary star is known as HAT-P-1, and the planet itself designated HAT-P-1b.〔 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「ADS 16402」の詳細全文を読む スポンサード リンク
