WASP-11/HAT-P-10 is a binary star consisting a magnitude-12 main-sequence orange dwarf star and M-dwarf with separation of 42 AU. The system is located about 400 light years away in the constellation Aries.[2] [6]

Planetary system

A semi-Jovian planet, WASP-11b/HAT-P-10b (WASP-11 A b/HAT-P-10 A b), has been detected in 2008 around the primary star by two projects independently using the transit method in a circular orbit around this star.[3][4]
