Constellation Centaurus the Centaur Star Map

Centaurus, the Centaur (Cen)

(cen-TAR-us)


The Southern constellation of Centaurus, the Centaur, is best viewed in Spring during the month of May. It's brightest star is Alpha Centauri at magnitude -0.27. The boundary of the Centaurus constellation contains 28 stars that host known exoplanets.

Centaurus is a circumpolar constellation, so is visible year-round in the Southern hemisphere. Conversely, it is not visible in the opposite hemisphere unless you are close to the equator.

Red supergiant V766 Centauri is the 9th largest known star in the universe at 1,300 times the size of the Sun.

            Neutron Stars in Centaurus

            These are the most well-known neutron stars in the constellation Centaurus. Although neutron stars cannot be seen in any amateur telescope, they are at the center of many supernova remnant nebulae, which can be seen. Also see all neutron stars.

              Black Holes in Centaurus

              These are the most well-known smaller (non-supermassive) black holes in the constellation Centaurus. 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. Also see all black holes.

                Exoplanets in Centaurus

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

                  * 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).
