The Alpha Centauri System

It has an estimated mass of 1. It is not yet known how habitable it is but the planet is subjected to stellar wind pressures of more than 2.

The planet was discovered in by the use of the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.

Much of this planet still remains a mystery. Since it is so close to us, the Alpha Centauri system will remain closely studied. The only planet detected has made enthusiasts striving for the discovery of possible other exoplanets in this system.

Many have been proposed but have yet to be confirmed. Since Proxima Centauri b is the closest exoplanet to us, a future mission is estimated to take place in and implement a search for habitable planets in the nearby star system.

Alpha Centauri System Facts Alpha Centauri is the closest star system and closest planetary system to the Solar System at 4. The two main stars Alpha Centauri A and B form a binary pair and are 4.

They are also named Alpha Centauri AB. To the naked eye, they appear to be one single star. They form the brightest star in the southern constellation of Centaurus and the third brightest in the night sky, outshone only by Sirius and Canopus.

The third star, Proxima Centauri is 4. Both Alpha Centauri A and B are Sun-like stars while Proxima Centauri is a small and faint red dwarf.

Some of this information may be preliminary and not entirely accurate as a result. The coordinate system is right ascension and declination.

Hours of RA are marked, as well as distance in multiples of 5 light-years. Image: DavidDarling. The Scottish astronomer Thomas James Henderson was the first to calculate the distance to Alpha Centauri using the parallax method between April and May from the Royal Observatory at the Cape of Good Hope.

He did not publish his findings until because he thought the results were too large to be accurate. Once Friedrich Wilhelm Bessel released his findings for the star 61 Cygni, also using the parallax method, in , Henderson decided to publish his own.

Technically, Alpha Centauri was the first star to have its parallax measured, but since it was not recognized first, it is generally considered as the second, after 61 Cygni in Cygnus constellation.

Henderson also realized that the components of the Alpha Centauri system displayed a significantly high proper motion. This means that Alpha Centauri moves about 1.

By the year 29,, Alpha Centauri will be at a distance of 3. Sirius will also brighten over the next 60, years and continue to be the brightest star for about , years.

After it has made its closest approach to the solar system, Alpha Centauri will gradually move away, until it reaches a final vanishing point in about , years.

The Alpha Centauri system may contain at least one planet, discovered in the orbit of Alpha Centauri B. The planet, if confirmed, will be the closest known exoplanet to Earth.

The nearby star system Alpha Centauri. Photo taken by Midcourse Space Experiment spacecraft. The star system has been the target for searches for decades because of its proximity to Earth, but previous studies have been unsuccessful in finding a planet orbiting any of the stars.

The first planet was discovered on 16 October by researchers at the Observatory of Geneva and the Centre for Astrophysics of the University of Porto.

They used the radial velocity technique. It took three years of observations to make an analysis. The planet is not in the habitable zone, as it orbits too close to the star, at only 0.

Alpha Centauri Bb orbits the star with a period of 3. It is possible that there are other planets orbiting Alpha Centauri A and B, but the searches have so far failed to find any gas giants or brown dwarfs.

For a planet to be in the habitable zone of Alpha Centauri A , it would need to orbit the star at a distance of around 1. At this distance, an Earth-like planet would have a similar temperature and conditions for liquid water to exist.

After the release of the expansion, multimedia producer Michael Ely wrote a trilogy of novels based on the game. Illustrator Rafael Kayanan also wrote a graphic novel entitled Alpha Centauri: Power of the Mindworms.

Mankind begins its most monumental task – the colonization of space. A crew of internationally renowned scientists and security strategists, with wide-ranging convictions and diverse ethics, embarks on a mission that will change the world. Sid Meier's Alpha Centauri is a 4X video game, considered a spiritual sequel to the Civilization in a science fiction depiction of the 22nd century, the game begins as seven competing ideological factions land on the planet Chiron ("Planet") in the Alpha Centauri star system. Alpha Centauri is by no means a graphically superior game; rather the opposite, actually. The maps, units, even buildings give a rough illusion of three dimensionality, but in truth, the entire game, much like other, older strategy titles, such as "StarCraft," is composed of the harsh, two dimensional graphics we have come to expect from. Alpha Centauri is a triple star system, with its two main stars, Alpha Centauri A and Alpha Centauri B, being a binary component. The AB designation, or older A×B, denotes the mass centre of a main binary system relative to companion star(s) in a multiple star system. [31]. The star Alpha Centauri is one of the brightest stars in the southern sky (marked with a red circle). It lies just light-years from the Earth and one component in a triple star system. Image.
