Kepler-32 is an M1V dwarf-type star located 1301.1 light years from Earth, in the constellation of Cygnus. Discovered in January 2012 by the Kepler spacecraft,[1] it shows a 0.58 ± 0.05 solar mass, a 0.53 ± 0.04 radius, and temperature of 3900.0 K, making it half the mass and radius of the Sun, two-thirds its temperature and 5% its luminosity.[2] It initially was known to have at least 2 planets orbiting around it, the smaller Kepler-32b, orbiting its parent star every 5.90124 days, and Kepler-32c with an orbital period of 8.7522 days.[3] In April 2013, transit-timing variation analysis confirmed 3 other planets to be in in the system. However, only very loose constraints of the maximum mass of the planets could be determined.[4]
