Sign in to saveWASP-42 is a K-type main-sequence star about 580 light-years away in the constellation Centaurus. Its surface temperature is 5315 K. WASP-42 is similar to the Sun in concentration of heavy elements, with metallicity ([Fe/H]) of 0.05, and is much older than the Sun at billion years. The star does exhibit starspot activity as is typical for its spectral class.
