HD 140913 is a star located in the constellation Corona Borealis (The Northern Crown) around 451 light-years away from Earth. With an apparent magnitude of 6.57, it is barely visible to the unaided eye on dark nights clear of light pollution. In reality it is a giant star that has cooled and expanded off the main sequence after exhausting its core hydrogen supply. It is around 1.9 times as massive as the Sun and has swollen to around 10 times its diameter and 45 times its luminosity.
