Planetary Prospects Around Centauri B

Centauri Dreams ^ | 01/19/10

Over twenty percent of the planets we’ve found around other stars inhabit binary systems. It’s intriguing to take a close look at these. Most of the planet-bearing binaries are what is known as ‘wide S-types,’ meaning that the companion star orbits the inner star/planet system at a distance of over 100 AU. But take a good look at GJ86b, γ Cephei b and HD41004b. Here we’re looking at three planets in close binary systems with a separation between the component stars of 20 AU or less. That separation raises the eyebrows, for Alpha Centauri A and B form a close binary with a semimajor axis of 23.4 AU.

If there is anything alive close to AC it could easily be on some small planet orbiting Proxima Centauri at some very close distance which would prevent our being able to detect it.

He stole that 'do from Patti LaBelle.

Maybe we can send James Cameron to “Pandora”... Permanently...
