Alpha Centauri Bb: An Interstellar Target?

Alpha Centauri Bb: An Interstellar Target? : Discovery News: "It may be too hot for life to survive on its surface, but the discovery of an Earth-sized planet orbiting Alpha Centauri B has ignited hope that the star -- one of two that orbit one another as a binary pair -- could play host to a whole system of rocky worlds.

The very fact that scientists using the European High Accuracy Radial velocity Planet Searcher (HARPS) telescope could detect the tiny gravitational tug of the orbiting world on its parent star is amazing enough, but the ramifications for the future of mankind have the potential to be nothing less than historic."
