WASP-29 is a binary star system 285 light-years (87 parsecs) away in the constellation of Phoenix. The primary star is a K-type main-sequence star. Its comoving companion, a red dwarf star, was discovered in 2021.[3] The star system kinematically belongs to the thin disk of the Milky Way.[5] The primary is an old star with small starspot activity and low x-ray flux.[6]
