WASP-11/HAT-P-10 is a binary star. It is a primary main-sequence orange dwarf star. Secondary is M-dwarf with a projected separation of 42 AU.[9] The system is located about 424 light-years away[1] in the constellation Aries.[2][10]
A semi-Jovian planet, WASP-11b/HAT-P-10b (WASP-11 A b/HAT-P-10 A b), was detected around the primary star independently by the Hungarian Automated Telescope Network and the Wide Angle Search for Planets teams, both of which used the transit method.[3][5]
