    Current estimates place the probability of finding an Earth-like planet around Alpha Centauri at roughly 75%. [125] The observational thresholds for planet detection in the habitable zones by the radial velocity method are currently (2017) estimated to be about 53 M E for Alpha Centauri A, 8.4 M E for Alpha Centauri B, and 0.47 M E for Proxima ...

    Estimates place the probability of finding a habitable planet around Alpha Centauri A or B at roughly 75%. [11] Alpha Centauri is the target of several exoplanet-finding missions, including Breakthrough Starshot and Mission Centaur, the latter of which is chronicled in the 2016 documentary film The Search for Earth Proxima.

    In February 2021, a new study proposed that, as the probability of a radio-transmitting civilization emerging on the Sun's closest stellar neighbour was calculated to be approximately 10 −8, the Copernican principle made BLC1 very unlikely to be a technological radio signal from the Alpha Centauri System.

  8. Alpha Centauri Ab - Wikipedia

    en.wikipedia.org/wiki/Candidate_1

    Candidate 1 (also known as C1 or Alpha Centauri Ab) is an exoplanet candidate directly imaged around Alpha Centauri A in February 2021. If confirmed as an exoplanet, it would orbit at approximately 1.1 AU away from Alpha Centauri A with a period of about a year and would have a mass between that of Neptune and one-half that of Saturn and would therefore likely be a giant planet. [1]

  9. Proxima Centauri - Wikipedia

    en.wikipedia.org/wiki/Proxima_Centauri

    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.
