You might need to look up that reference. As reported on Wired.com.....
Astronomers have discovered an exoplanet roughly the size of Earth orbiting Alpha Centauri B, the star nearest our sun.
The Alpha Centauri system — composed of three stars orbiting one another — is only 4.4 light-years away, a cosmic stone’s throw from us. Though the newly discovered planet has about the same mass as our own, its orbit is 25 times smaller, so a year on this planet passes in just 3.2 days. This means the planet is sitting up against its star, roasting at perhaps 2,200 degrees Fahrenheit with a surface likely composed of molten lava.
