KELT-24 (HD 93148, MASCARA-3) is a single star in the constellation Ursa Major at a distance of approximately 316 light-years (about 96.8 parsecs) from Sun. The apparent magnitude of the star is +8.33m. The star's age is estimated to be about 1.6 billion years.[2][3][4] As an F-type main-sequence star, it is similar to the Sun, but slightly hotter and more luminous.
