Alpha Centauri

  The Alpha Centauri system is the closest star system to our sun.

  • it is 4.37 light-years (1.34 pc) from the Sun.

  • Light Years :- a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 million million miles).
  • It consistsof three stars.
    • Alpha Centauri A. (also named Rigil Kentaurus).
    • Alpha Centauri B. (also named proxima centauri).
    • Alpha Centauri C

Since 1988, scientists have found more than 3,000 planets orbiting stars other than our sun. The newest addition is Proxima Centauri b, a small, rocky world just 4.24 light-years away, which may be in a habitable orbit.


The journey to Alpha Centauri B orbit would take about 100 years, at an average velocity of approximately 13411 km/s, about 4.5% the speed of light, and another 4.39 years would be necessary for the data to reach Earth.

It would take tens of thousands of years to make the 4.37-light-year trip using the best rocket propulsion that’s available today (30 km/s).
