Only 25 4 Trillion Miles Away Earth Sized Planet Found At Alpha Centauri B
European researchers have detected a planet -- just slightly more massive than Earth -- orbiting very close to Alpha Centauri B, a sun-like star only 4.3 light-years (about 25.4 trillion miles) from our Sun. Orbiting once every 3.2 days, the planet known as ALPHA CENTAURI BB is not in the habitable zone however. The surface temperature is estimated to be 2,200 degrees Fahrenheit. David Brodie explains in the above video for Space.com.

The planet adds to the growing number of EXTRASOLAR PLANETS frequently being found around other stars throughout the Milky Way. Anan imaginary journey from Earth to the Alpha Centauri system is animated in the foregoing video. Departing the Solar System, one sees the familiar constellation figures including the Southern Cross (Crux) and the bright stars Alpha and Beta Centauri. In the approach Alpha Centauri a faint red star is passed. The star is Proxima Centauri, the closest star to Earth and the faintest component of a triple star system. The final part shows the bright double star Alpha Centauri A and B with the Sun visible in the background.
