          Black Holes in Monoceros

          These are the most well-known smaller (non-supermassive) black holes in the constellation Monoceros. Although black holes cannot be seen directly, the smaller ones are at the center of some star clusters and supernova remnant nebulae, which can be seen. Supermassive black holes are at the center of most galaxies, such as Sagittarius A* at the center of our Milky Way galaxy.

            Exoplanets in Monoceros

            These are the most notable named exoplanet systems known in the constellation Monoceros. Bear in mind that we will likely discover billions of exoplanets in the years to come.

              * For southern latitudes, flip the season listed. For example, if a constellation is listed as best viewed in the summer in the month of July, in the southern hemisphere the constellation would be best viewed in the winter in January and would be upside-down.

              ** Circumpolar constellations are visible year-round in the hemisphere listed (and not at all in the opposite).
