The

Its story

Theta Gruis is not one star but three: a magnetic F-type primary, similar to Delta Delphini, with a faint close companion and a Sun-like third star orbiting further out. It lies 132 light-years away in the southern Crane, and the main star spins at 64 km/s with twenty-seven times the Sun's luminosity. Three interlaced suns reduced to a single white point of light for the naked eye.
