Theta Delphini
Theta Delphini is a star in the constellation Delphinus. It has an apparent magnitude of about 5.7, meaning that it is just barely visible to the naked eye under excellent viewing conditions. This star is around 2,050 light years away from the Sun.
Theta Delphini's spectral type is K3Ib, meaning it is a K-type supergiant. These types of stars form when relatively massive stars like B-type main sequence stars run out of hydrogen to fuse and start cooling down. It has been described as a super-metal-rich star because of its high metallicity
