he first results are in — and yes, there is at least one planet orbiting Alpha Centauri B, one of the three stars clustered together there. European astronomers, using a 3.6 meter telescope at the La Silla Observatory in Chile, report it is remarkably small — about as massive as Earth. Worlds that small have been beyond earthlings’ capacity to detect them until just very recently.
Let’s get some details out of the way quickly. The newly found planet is probably hellish, only about 4 million miles from its host star (we’re 93 million miles from ours). It’s also fast, completing one orbit — one “year” — in only 3.2 of our days.
Doesn't sound like a great place to visit, though.
