  2. Alpha Centauri - Wikipedia

    en.wikipedia.org/wiki/Alpha_Centauri

    For this reason, Alpha Centauri is sometimes considered as the second star to have its distance measured because Henderson's work was not fully acknowledged at first. [66] (The distance of Alpha Centauri from the Earth is now reckoned at 4.396 light-years or 4.159 × 10 13 km.)

    The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A, which is also the brightest star in Earth's night sky; its white dwarf

  5. Proxima Centauri - Wikipedia

    en.wikipedia.org/wiki/Proxima_Centauri

    Proxima Centauri b, or Alpha Centauri Cb, orbits the star at a distance of roughly 0.05 AU (7.5 million km) with an orbital period of approximately 11.2 Earth days. Its estimated mass is at least 1.07 times that of the Earth . [ 16 ]

  6. Proxima Centauri b - Wikipedia

    en.wikipedia.org/wiki/Proxima_Centauri_b

    Proxima Centauri b is the closest exoplanet to Earth, [20] at a distance of about 4.2 ly (1.3 parsecs). [5] It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 AU, [1] over 20 times closer to Proxima Centauri than Earth is to the Sun. [21] As of 2021, it is unclear whether it has an eccentricity [e] [24] but Proxima Centauri b is unlikely to have any obliquity. [25]

    On this scale, the distance to Alpha Centauri A would be 276 kilometers (171 miles). The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/390 of a light-year in 46 years and is currently moving at 1/17,600 the speed of light. At this rate, a journey to Proxima Centauri would take 75,000 years. [2] [1]

    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.
