KELT-21b is an extrasolar planet discovered in 2018. It is a hot Jupiter with radius of about 1.586 MJ. [1]
KELT-21b orbits KELT-21 A (HD 332124). It is likely the primary star in a triple star system, with the two stars located 1.2 arcseconds away. These two stars, designated KELT-21 B and C, have masses of 0.13 M☉ and 0.11 M☉, respectively. [1]
