The primary and secondary have a period of 80 years and will be closest to each other as seen from Earth in 20.In addition to Alpha Centauri (the third-brightest star in the sky), a second first magnitude star, Beta Centauri, is part of Centaurus.

The Blue Planetary was discovered by John Herschel and named for its color's similarity to Uranus, though the nebula is apparently three times larger than the planet. NGC 4622 is a face-on spiral galaxy located 200 million light-years from Earth (redshift 0.0146).

Its spiral arms wind in both directions, which makes it nearly impossible for astronomers to determine the rotation of the galaxy.

Alpha Centauri, the closest star system to the Sun, has a high proper motion; it will be a mere half-degree from Beta Centauri in approximately 4000 years.

Alpha Centauri is a triple star system that contains Proxima Centauri, the nearest star to the Sun.

Proxima, the tertiary star, is a red dwarf of magnitude 11.0; it is almost 2 degrees away from the primary and secondary and has a period of approximately one million years.

Also a flare star, Proxima has minutes-long outbursts where it brightens by over a magnitude.Taken with Canon 85mm f/1.8 lens with 11 frames stacked, each frame exposed 30 seconds. This image is reversed from what one sees looking at the sky — it is as though one is looking at the "celestial sphere" from the outside. Its alpha and beta stars are used as "pointer stars" to help observers find the constellation Crux.Centaurus in the Firmamentum Sobiescianum of Johannes Hevelius. Centaurus has 281 stars above magnitude 6.5, meaning that they are visible to the unaided eye, the most of any constellation.The two bright stars are (left) Alpha Centauri and (right) Beta Centauri.The faint red star in the center of the red circle is Proxima Centauri.In the eyepiece, it is a small galaxy of magnitude 10 with dimensions of 5 arcminutes by 2 arcminutes and a bright nucleus.
