SIMBAD	data

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]

The star is likely older than Sun, has fraction of heavy elements close to solar abundance, and is rotating rapidly, being spun up by the tides raised by the giant planet on the close orbit.^[3]

WASP-10b

WASP-10b is an extrasolar planet discovered in 2008.^[4]

WASP-10c

WASP-10c is an unconfirmed as in 2020^[5] extrasolar planet inferred from transit time variations of WASP-10b's transits. It was discovered in 2010.^[6]

High likelihood of another Super-Jupiter planet at wide (at least 5 astronomical units) orbit was reported in 2013.^[7]
