Following the historic discovery of the first extrasolar planet, 51 Pegasi b, in 1995 (Mayor and Queloz, 1995) more than 200 planets orbiting other stars have now been catalogued. The vast majority of these planets have been detected with the radial velocity technique, which is biased towards heavy, close-orbiting planets. However, the number of lighter, more distantly orbiting known exoplanets is increasing steadily and, in addition, a growing fraction of exoplanets have now been discovered using other detection methods that may be more successful in detecting terrestrial-type planets. In this chapter we will review the main physical properties of the exoplanets (and their parent stars) discovered to date (28 February 2007) and will review the expectations of forthcoming observations.
