Among the many exoplanets now being discovered, Fomalhaut B was considered something special – the first exoplanet to be directly photographed in visible light, by the Hubble Space Telescope, back in 2008. That is, until more recent studies suggested that it might not be real, not even a planet after all.

An amazingly wide variety of exoplanets are now being discovered orbiting other stars and some of the most interesting are those referred to as “super-Earths,” rocky worlds which are typically a little larger to a few times bigger than Earth.

This has been a good week for exoplanets – first the reported discovery of a world with four suns, and now something that many people had been hoping for, a planet in the closest star system to Earth, Alpha Centauri!

Until recently, astronomers only knew about exoplanets which, like those in our own solar system, orbited a single star. Then, the first one was discovered which orbits two stars, much like Tatooine in the Star Wars films. Since then, other similar planets have been found, indicating that such circumbinary planets (those which orbit double stars) may be fairly common.
