WASP-11, also designated HAT-P-10, is a binary star system. The primary star is a main-sequence orange dwarf star. The secondary is an M dwarf with a projected separation of . The system is located about 424 light-years away in the constellation Aries.

Planetary system

A hot Jupiter with half Jupiter's mass, WASP-11b (or HAT-P-10b), 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.
