Alpha Centauri is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus, Toliman (B) and Proxima Centauri (C). Proxima Centauri is the closest star to the Sun at 4.2465 light-years.
Proxima Centauri is a small, low-mass star located 4.2465 light-years (1.3020 pc) away from the Sun in the southern constellation of Centaurus. Its Latin name means the 'nearest [star] of Centaurus'. It was discovered in 1915 by Robert Innes and is the nearest-known star to the Sun. With a quiescent apparent magnitude of 11.13, it is too faint to be seen with the unaided eye. Proxima Centauri is a member of the Alpha Centauri star system, being identified as component Alpha Centauri C, and is 2.18° to the southwest of the Alpha Centauri AB pair. It is currently 12,950 AU (0.2 ly) from AB, which it orbits with a period of about 550,000 years.
Orphans of the Sky is a science fiction novel by American writer Robert A. Heinlein, consisting of two parts: "Universe" and its sequel, "Common Sense". The two novellas were first published together in book form in 1963. "Universe" was also published separately in 1951 as a 10¢ Dell paperback. The work presents one of the earliest fictional depictions of a generation ship.
"The Variable Man" is a science fiction novella by American writer Philip K. Dick, which he wrote and sold before he had an agent. It was first published in the British magazine Space Science Fiction Vol. 2 No. 2, July 1953, and in the American version on September 1953, with the US publication illustrated by Alex Ebel. Despite the magazine cover dates it is unclear whether the first publication was in the UK or in the United States where magazines tended to be published farther ahead of their cover dates than in the UK. The Variable Man can be found in several collections of Dick's short stories, including The Variable Man and The Short Happy Life of the Brown Oxford.

"Rautavaara's Case" is a science fiction short story by American writer Philip K. Dick. It was first published in 1980 in Omni magazine and subsequently in the 1985 short story collection I Hope I Shall Arrive Soon. The story was also included on We Can Remember It For You Wholesale, volume five of the Collected Short Stories of Philip K. Dick in 2003.
Alpha Centauri is a star system and the collective name of three stars in that system. The individual stars are named Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.
The Bayer designations c Centauri and C Centauri are distinct.
"Proxima Centauri" is a science fiction short story by American writer Murray Leinster, originally published in the March 1935 issue of Astounding Stories. Unusually for the time, the story adhered to the laws of physics as they were known by showing a starship that was limited by the speed of light and took several years to travel between the stars. In his comments on the story in Before the Golden Age, Isaac Asimov thought that "Proxima Centauri" must have influenced Robert A. Heinlein's later story "Universe" and stated that it influenced his own Pebble in the Sky.

Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail interstellar probes named Starchip, to be capable of making the journey to the Alpha Centauri star system 4.34 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark Zuckerberg.
Proxima Centauri b, sometimes referred to as Alpha Centauri Cb, is an exoplanet orbiting within the habitable zone of the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of the larger triple star system Alpha Centauri. It is about 4.2 light-years from Earth in the constellation Centaurus, making it and Proxima d, along with the currently disputed Proxima c, the closest known exoplanets to the Solar System.
Proxima Centauri c is a controversial exoplanet candidate claimed to be orbiting the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of a triple star system. It is located approximately 4.2 light-years from Earth in the constellation of Centaurus, making it, Proxima b, and Proxima d the closest known exoplanets to the Solar System.
BLC1 was a candidate SETI radio signal detected and observed during April and May 2019, and first reported on 18 December 2020, spatially coincident with the direction of the Solar System's closest star, Proxima Centauri.
Proxima Centauri d is an exoplanet orbiting the red dwarf star Proxima Centauri, the closest star to the Sun and part of the Alpha Centauri triple star system. Together with two other planets in the Proxima Centauri system, it is the closest known exoplanet to the Solar System, located approximately 4.2 light-years away in the constellation of Centaurus. The first signs of the exoplanet emerged as a weak 5.15-day signal in radial velocity data taken from the Very Large Telescope during a 2020 study on Proxima b's mass. This signal was formally proposed to be a candidate exoplanet by Faria et al. in a follow-up paper published in February 2022.
