BBC NEWS | Science & Environment | Telescope sees smallest exoplanet.

The smallest planet yet found outside the Solar System has been detected by a French space telescope.

The rocky world is less than twice the size of Earth.

Only a handful of planets have so far been found with a mass comparable to Earth, Venus, Mars or Mercury.

The discovery was made by Corot, an orbiting observatory with a 27cm-diameter telescope to search for planets orbiting other stars.
