Alpha Centauri is located just over four light years (光年), or about 25 trillion miles, from Earth. It would take today’s spacecraft more than 70,000 years to reach the star system. While this seems a very long distan...
Alpha Centauri is the closest star system to Earth and is made up of three stars and several exoplanets. We explore our stellar neighbors in more detail here.
ALPHA CENTAURI C (PROXIMA CENTAURI)is a smaller red dwarf star with a much larger orbit. Because of its orbit, Proxima Centauri is the closest star to Earth. This diagram illustrates the locations of the star systems closest to the sun. The year when the distance to each system was determi...
This is a very fine double star. Sadly, its Southern position makes it out of reach for a lot of people. I had a chance to view this pair on 4/2/2022. Alpha Centauri usually hides behind my neighbor's rooftop so I need a telescope which is high enough to reach to this double. I...
This is also the nearest star system to the Solar System. Alpha Centauri (credit:- ESO/Digitized Sky Survey 2/Davide De Martin) Unusual for a bright star, Alpha Centauri does not have a commonly agreed proper name. Arab astronomers called it "Rigil Kentaurus", meaning "the foot of the ...
The article reports on the discovery of an earth-sized planet in the Alpha Centauri star system by European astronomers. It notes that Alpha Centauri is the nearest neighbor of the Earth and is comprised of three stars and a newly discovered planet. It is said that the planet is orbiting ...
Alpha Centauri is the closest star system to the Solar System. Image released Oct. 17, 2012. (Image credit: ESO/Digitized Sky Survey 2) Rigel Kentaurus is the third-brightest star in the night sky. However, its brightness is due to the proximity of the system — commonly known as ...
New Mission to Scour Alpha Centauri System for Life November 17, 2021 A new space mission to hunt for potentially habitable planets around Earth’s closest neighbouring star system is under way.In a project with echoes of the 2009 film Avatar, an international collaboration of scientists in Austr...
Swinney, "Navigation to the Alpha Centauri star system", JBIS, 69, pp.379-389, 2016 In this paper we reconsider the navigation issues for the specific case of the Alpha Centauri system that Project Icarus has selected as its mission target. In a companion paper the generic case issues for...
Alpha Centauri is the closest star system to the Solar System. Image released Oct. 17, 2012. (Image credit: ESO/Digitized Sky Survey 2) Stephen Hawking, Yuri Milner and Mark Zuckerberg helm the board for a new initiative, Breakthrough Starshot, whose technology could be used to someday ...
