Doppler shifts of FGKM-type main sequence stars are routinely measured with a precision of 3 m/s, enabling detection of orbiting planets. To date, 36 extrasolar planets have been identified, including the first system of multiple planets and the first transiting planet (Henry et al. 2000; Charbonneau et al. 2000). The distribution of planet masses rises steeply from 8 Mjup toward sub-Jupiter masses, and two planets have Msini less than the mass of Saturn. All 24 planets beyond 0.2 AU from their star reside in eccentric orbits with e>0.1, with no circular orbits yet found among them. Future Doppler measurements must maintain precision of 2 m/s to detect true analogs of Jupiter at 5 AU.
