WASP-103
Sign in to saveWASP-103 is an F-type main-sequence star located 1,800 ± 100 light-years (550 ± 30 parsecs) away in the constellation Hercules. Its surface temperature is (K). The star's concentration of heavy elements is similar to that of the Sun. WASP-103 is slightly younger than the Sun at 4 billion years. The chromospheric activity of the star is elevated due to interaction with the giant planet on a close-in orbit.
