stellar mass density - EAS
- Stellar density is the average number of stars within a unit volume. It is similar to the stellar mass density, which is the total solar masses (M Sun) found within a unit volume. Typically, the volume used by astronomers to describe the stellar density is a cubic parsec (pc 3).
