Delta Circini
An immensely distant, but highly luminous star that lies nearly 6,400 light years from Earth. The main star in this system is of the intensely hot O-type classification, with a surface temperature of 25,000 K or even greater. It has a companion star, apparently a yellow dwarf like our own Sun, whose orbit causes the apparent magnitude of the entire system to vary.
