HAT-P-1

ADS 16402 is a binary star system, composed of two sun-like stars located approximately 525 light-years away in the constellation Lacerta. It was first identified as a binary star by John Herschel in 1831. [5] The two stars are separated by 11.26 arcseconds which leads to a projected separation of roughly 1500 astronomical units at the distance of ADS 16402. The star system is estimated to be 1.9 ± 0.6 billion years old. [8] The secondary star ADS 16402 B is also designated HAT-P-1.

Planetary system

On September 14, 2006 the HATNet Project announced their first extrasolar planet discovery HAT-P-1b, a hot jupiter type gas giant in orbit around the secondary star ADS 16402B. 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. [5] [13]
