Planets

For over ten years astronomers have been finding planets circling stars other than the Sun. The number has been increasing at a phenomenal rate and, as of the end of November, the total number of extra-solar planets stands at 170. These break down into 146 different systems, 18 of which have multiple planets. Currently, these planets are all very big - about the size of Jupiter or larger - and the hunt is on for the first detection of an Earth-mass planet. The trouble is that the bigger planets are easier to find than little ones.

Future space missions such as Kepler and Gaia should find more planets than you can shake a stick at.
