  Eddington is a space mission for extrasolar planet finding and for
asteroseismic observations. It has been selected by ESA as an F2/F3 reserve
mission with a potential implementation in 2008-13. Here we describe
Eddington's capabilities to detect extrasolar planets, with an emphasis on the
detection of habitable planets. Simulations covering the instrumental
capabilities of Eddington and the stellar distributions in potential target
fields lead to predictions of about 10,000 planets of all sizes and
temperatures, and a few tens of terrestrial planets that are potentially
habitable. Implications of Eddington for future larger scale missions are
briefly discussed.
