NGC 2421 is a young open cluster in the Puppis constellation. NGC 2421 is located close to the celestial equator which makes it somewhat visible from both hemispheres in certain times of the year. This cluster was first studied by Moffat and Cogt in 1975 and presumed to have a distance of approximately 1.87 kpc. […]
