==Description== KELT-2A is the primary star in the common-proper-motion binary star system KELT-2 (HD 42176). It is an F-type main sequence star about 1.314 times as massive as the sun. It has about 1.84 times the Sun's radius and radiates 3.5 times the Sun's luminosity at a temperature of about 6148 K. It is 3.97 billion years old and has a rotational velocity of around 9 km/s. KELT-2B is an early K dwarf approximately 295 AU away, which was discovered simultaneously with the planet KELT-2Ab in 2012. It has 78% of the Sun's mass, 70% of its radius, and an effective temperature of .
