HD 93607 (HR 4222) is a star in the constellation Carina. Its apparent magnitude is 4.87. Its parent cluster is IC 2602.
HD 93607 is a B4 main sequence star, although older spectral studies classified it as a subgiant. [7] It is included on a list of the least variable stars amongst those observed by the Hipparcos satellite, with a possible variation less than 0.01 magnitudes. [8]
HD 93607 lies in the core region of the bright open cluster IC 3602. Its age is uncertain but around 17 million years. [5]
