While topological features on Solar System bodies — such as craters, mountains, and valleys — are often named after famous or historical individuals, many stars and deep-sky objects are named after the individual(s) who discovered or otherwise studied it.
This list does not include astronomical objects named after mythological or fictional characters.
Comet names are often given for the astronomer(s) who discovered it, but they can also be for scientists who gave significant contributions towards their study.
In most cases, the named individual was the person who discovered the galaxy, who first brought attention to it, or who first studied it scientifically.
Objects in these catalogs are excluded below, except in cases where they carry the name of an additional person.
