They Found The Closest Exoplanet: Alpha Centauri Bb

Alpha Centauri is the closest known star system to us at just over 4 light years away.  Perhaps we should be spending more effort examining that area for signs of life.  And just a few years ago in 2012 they made a cool discovery:

The closest star system to our own is now confirmed to have at least one earth-sized extrasolar planet, discovered by European Space Agency Astronomers working at the Observatory of Geneva.

The planet, called Alpha Centauri Bb, orbits the K-type star Alpha Centauri B, a star slightly 90.7% of the Sun’s (G-type) mass and 50.0% of its luminosity.

Let’s find out more about this solar system and check out a cool simulaition video on page 2
