Hey neighbor: Astronomers find an Earth-like planet just next door in Alpha Centauri, the nearest star system to our sun. “Indeed, Alpha Centauri Bb is the first planet with an earth-like mass ever found orbiting a sun-like star.” That being said, prospects for life — or colonization — seem, for the time being, remote. “Unfortunately for any hope of finding life on this world, it orbits only about four million miles away…This would make Alpha Centauri B more than twenty times larger in the planet’s sky than the sun is here on earth…and more than 500 times brighter and hotter.”
