Alpha Centauri A may have a Neptune-sized habitable-zone planet, though it is not yet known to be planetary in nature and could be an artifact of the discovery mechanism. Alpha Centauri B has no known planets: planet Bb, purportedly discovered in 2012, was found to be an artifact, and a separate transiting planet has yet to be confirmed.

The Robinson family in "Lost in Space" (1960's TV program) were on their way to Alpha Centauri to visit what was expected to be a habitable planet and haven for Earth's over-populated masses. Alpha Centauri a and b are quite close together. A planet trying to form around either star, would probably be disrupted by the gravity of the other, or have its orbit affected to the point that it was thrown into its parent star, or out of the star system entirely. The Hunt Is On for Alpha Centauri’s Planets Interstellar Intimates. The lure of Alpha Centauri is easy to understand: For the scientists yearning to find living Lighthouses and Fireflies. Presuming that the wobble searches are successful in finding planets around Alpha Centauri, Breakthroughs Nach Angaben der Astronomen könnte es in der habitablen Zone um Alpha Centauri A Planeten von bis zu 50 Erdmassen geben – bis zu dieser Grenze reichte die bisherige Auflösung. Alpha Centauri B Astronomers first realized the bright star Alpha Centauri was a tightly orbiting pair in 1689, and Proxima Centauri was first spotted in 1915.

Alpha centauri planets

In 2012, researchers used an instrument called the Sarah Rugheimer of Oxford University followed, pointing out that biosignatures on exoplanets—signs indicating the presence of life—would change over time. Earth’s own history reveals how many different types of atmosphere a planet can have over time, which presumably would hold true in the Alpha Centauri triple star system as well. Astronomers have spotted “something” near Alpha Centauri A, in the star system nearest our Earth and sun. If it turns out to be a planet, it’ll be the first time a planet has been directly imaged The extraterrestrials from Alpha Centauri vibrate and resonate on the band of violet light.

New research is bringing us (2008), the situation would appear to be that if planets do not exist within the α Centauri system, then we have seriously misunderstood how planet formation works 12 Apr 2020 Didier Queloz talks about realistic ways to explore Proxima Centauri b and other potentially habitable planetary systems such as TRAPPIST-1.

Alpha Centauri was discovered in 1915, while it’s only confirmed planet, Proxima Centauri b, was discovered in 2016 and it is the closest exoplanet to us. The two main stars Alpha Centauri A and B form a binary pair and are 4.3 light-years away from Earth. They are also named Alpha Centauri AB. To the naked eye, they appear to be one single star.

(ENT - Rise of the Federation novel: A Choice of Futures; ENT novel: The Good That Men Do; ST novel: Articles of the Federation) In FASA RPG module: The Federation, the Alpha Centauri state was Proxima Centauti b [1] is the only confirmed planet in the Alpha Centauri system, orbiting Proxima Centauri—discovered in 2016 [2]—it orbits its star at a distance of 0.05 AU, and possibly has a rocky composition. In fact, if our nearest neighbour Alpha Centauri has Earth-sized planets, we should be able to detect them with established techniques… right now, with the observatories we have today.

The star is Alpha Centauri A, just 4.4 light-years away, in the star system nearest our Alpha Centauri a and b are quite close together. A planet trying to form around either star, would probably be disrupted by the gravity of the other, or have its orbit affected to the point that it was thrown into its parent star, or out of the star system entirely. Abstract: $\alpha$ Centauri A is the closest solar-type star to the Sun and offers the best opportunity to find and ultimately to characterize an Earth-sized planet located in its Habitable Zone (HZ). Here we describe initial results from an ALMA program to search for planets in the $\alpha$ Cen AB system using differential astrometry at

Alpha Centauri is a triple-star system, composed of a binary star, two stars much like the Sun - one slightly larger and hotter, called Alpha Centauri A, and the other slightly smaller and cooler, called Alpha Centauri B - orbited themselves by a red dwarf (called Proxima Centauri) much farther out. The planet orbits close in to Alpha Cen B

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. Bottom line: Astronomers may have directly imaged the first-ever planet within the habitable zone of a star.
