    The Alpha Centauri system refers to the closest stars and exoplanets to Sunball. The Alpha Centauri system consists of three stars: Rigil Kentaurusball (Alpha Centauri A), Tolimanball (Alpha Centauri B), and Proxima Centauriball (Alpha Centauri C). The system is located four light-years away in the constellation of Centaurus, from which the system gets its name. Finally, there might be 6balls here.

    Although Alpha Centauri is a triple-star system, the details are more complicated. Rigil Kentaurusball and Tolimanball are a binary system, in which both stars orbit a barycenter. Proxima Centauriball orbits the pair with a semi-major axis of ~8700 AU. Proxima Centauriball itself can into planets: Proxima Centauri dball is a sub-Earth[1] that orbits at a distance of 0.029 AU away. Proxima Centauri bball is similar to Earthball and orbits at the inner edge of the habitable zone, at 0.049 AU. Lastly, the controversial Proxima Centauri cball is a gas dwarf[2] that possibly may into rings. If it exists, it orbits at a distance of 1.5 AU.

    Rigil Kentaurusball

    Rigil Kentaurusball is a yellow dwarfball of spectral class G2V as is the primary member of the binary system. It has 10% more mass than Sunball and is 22% larger. Take, than Sun!

    Rigil Kentaurusball has an unconfirmed candidate named Candidate 1ball that, if it can into exist, would be 1.1 AU away. Its nature is likely a mini-Neptune, but if it has moons, they could be habitable.


    Tolimanball is an orange dwarfball with spectral class K1V. Compared to Sunball, Tolimanball is 90% as massive and is 14% smaller. It is also slightly more active than Rigil Kentaurusball.

    Scientists on Earthball detected a transit-like event in 2013. They attributed this event to a planet, nicknamed Alpha Centauri Bc. It would be slightly smaller than Earthball with an orbital period of 20.4 days. This means it cannot into 6balls, as it is too close. As of 2023, this exoplanet candidate has not been confirmed.

    Proxima Centauriball

    Main article: Proxima Centauriball

    Proxima Centauriball is a red dwarf with spectral class M6Ve. It has two (possibly three) planets and itself orbits the Alpha Centauri AB binary system. Proxima Centauriball itself is the closest star to Sunball.

    Planetary System

    • A:
      • Candidate 1 (unconfirmed)
    • B:
      • None
    • C:
      • Proxima Centauri d
      • Proxima Centauri b
      • Proxima Centauri c (disputed)


    • Sunball - Thinks they are better then me because one of its planets has life i might have 6ball!!
    • Proxima Centauriball - My favorite star in the universe that also orbits me!


    1. For reference, Marsball and Mercuryball are also sub-Earths
    2. Also known as a "Mini-Neptune"
