WASP-10 is a star in the constellation Pegasus. The SuperWASP project has observed and classified this star as a variable star, perhaps due to the eclipsing planet.[2]

WASP-10b is an extrasolar planet discovered in 2008.[3]
WASP-10c is an unconfirmed as in 2020[4] extrasolar planet inferred from transit time variations of WASP-10b's transits. It was discovered in 2010.[5]
High likelihood of another Super-Jupiter planet at wide (at least 5 astronomical units) orbit was reported in 2013.[6]
