  1. The closest star system to the Earth is the famous Alpha Centauri group. This NASA/ESA Hubble Space Telescope has given us this stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right), shining like huge cosmic headlamps in the dark.
  2. The Alpha Centauri system is a trinary system with thirteen planets, the nearest star system to the Sol system, light years distant. The first star system beyond Sol to be colonized by humans, it was home to the indigenous Alpha Centauran culture. In the year , astronomers on Earth, using ground-based adaptive optic telescopes, resolved at least two bodies in the Alpha Centauri system.
  3. Alpha Centauri, also called Rigil Kentaurus, triple star, the faintest component of which, Proxima Centauri, is the closest star to the Sun, about light-years distant. The two brighter components, called A and B, about light-year farther from the Sun, revolve around each other with a period of about 80 years, while Proxima circles them with a period of , years.
  4. Of the three stars in the system, the dimmest -- called Proxima Centauri -- is actually the nearest star. The bright stars Alpha Centauri A and B form a close binary as they are separated by only 23 times the Earth- Sun distance - slightly greater than the distance between Uranus and the Sun. In the above picture, the brightness of the stars.
  5. Alfa Centauri (α Centauri, zkráceně α Cen) je trojhvězda a svou vzdáleností 4,37 světelného roku (1,34 parseku) také nejbližší hvězdný systém od sluneční vepimunchsforcomsofrresofttansecharju.xyzinfoává ze tří složek: společné dvojice Alfa Centauri A (též Rigil Kentaurus) a Alfa Centauri B (též Toliman) a malého a vizuálně slabého červeného trpaslíka Alfa Centauri C (též Proxima Centauri.
  6. Alpha Centauri is a trinary star system consisting of the three companion stars Rigil Kentaurus, Quindar and Proxima. At a little over four light-years distant, this is the closest star system to Earth in the Sol system.
  7. Alpha Centauri (α Cen / α Centauri) is the brightest star system (a triple star system) in the southern constellation of Centaurus, and contains the fourth brightest star in the night sky.
  8. Pluto Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter Proxima Centauri b Alpha Centauri B b Alpha Centauri B c Habitable zone. The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). This is only an estimate, using the star's spectral type.
  9. Nov 18,  · Alpha Centauri is the name given to what looks like the closest star to us in the night sky. This is only when observed with the naked eye. It actually is a star system comprised of three stars: the binary star system of Alpha Centauri A and Alpha.
