There have already been some searches of the alpha Centauri system for habitable planets. In 2012, Xavier Dumusque and collaborators reported the possible detection of an Earth-mass planet in a scorching three-dayorbitaround alpha Centauri B. This possible discovery was based on years of radial v...
When Wang and colleagues applied thedevolitization modelto Alpha Centauri A and B, the C/O ratio came out higher, at 0.65. Any planets in this system would therefore be enriched with more carbon-bearing minerals, although how much carbon would exist on their surfaces remains unclear. Previous...
“There is not a more exciting result for an individual star, even with the long line of spectacular results from the last two decades,” says Debra Fischer (Yale), who has spent years searching for planets in the Alpha Centauri system but was not involved with the new study. Astronomers ...

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.
2012 online issue of the journal "Nature" reporting the discovery of a planet orbiting the star Alpha Centauri B with a mass similar to Earth's using the High Accuracy Radial Velocity Planet Searcher (HARPS), the possibility that other rocky planets may be in the same system, and follow-up...
This is why NASA plans to launch a probe towards Alpha Centauri in 2069. The intent of this interstellar space mission is to search for biosignatures on planets around the stars in the Alpha Centauri system. Even here in ourMilky Way galaxy, there are at least 10 possible habitable planets...
If thenearest star system, Alpha Centauri, does harbor rocky planets similar to Earthas new findings suggest, there exist a host of ways to get us there, in theory. Sending aperson to Alpha Centauri within a human lifetime wouldn't be easy. AlphaCentauri is 4.37 light-years away ? more ...
How many planets are in the Alpha Centauri system? How far is Mars from Earth? Is Alpha Centauri in our galaxy? How far away can the Hubble Space Telescope detect galaxies? How far is Earth from the sun in astronomical units? How far has the Hubble Telescope traveled?
This week's discovery of an Earth-size planet orbiting a star in the Alpha Centauri system — the closest to our own solar system — may have you eager to find out more. You could wade into the vast reaches of the Internet, or you could reach into your pocket and use an app. One ...
