		| Abstract: | 
		One hundred extrasolar planets have been discovered, all with ground-based Doppler observations. Most of the detected planets have masses (M sin i) greater than Jupiter. However, with improved precision the Doppler technique should eventually reach down to Neptune-mass planets at separations of 1 AU or less. Here we present the characteristics of discovered planets and their host stars and we report two multiple planet discoveries.  |
