Alpha Centauri B has Planets

Alpha Centauri B has planets! The two stars of the Alpha Centauri binary system are the closest stars to our Sun, a mere 4.36 light years away. The newly discovered planet orbits very close to its star, but it seems to be about the same size as Earth and its orbit has ripples that may indicate other worlds farther out.

Of course, 4.36 light years is still 25.6 trillion miles, or 41.2 trillion kilometers, so to get there in a reasonable time will still take a warp drive.
