List of astronomical objects named after people

This is a list of astronomical objects named after people. 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.

Comets

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.

Interstellar comets

2I/Borisov is the first observed interstellar comet, named after Gennadiy Borisov

Great comets

Periodic comets

Craters

Galaxies

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. Many of the brighter galaxies visible from the Northern Hemisphere have Messier numbers, named after Charles Messier. There are a few other comprehensive catalogs that assign the cataloguer's name to galaxies. For instance, Markarian galaxies, named after Benjamin Markarian, are galaxies with excess blue and ultraviolet emission;^[5] galaxies in the Atlas of Peculiar Galaxies are assigned an Arp number after Halton Arp who produced the catalog; etc. Objects in these catalogs are excluded below, except in cases where they carry the name of an additional person.
