This indicates the minimum mass of 1.69 Jupiter mass, an orbital period of 386.3 days, and the semi-major axis of 1.07 astronomical units based from its stellar mass. The wild, oval pathed wobble of the star used by Doppler spectrometer indicates that the orbit of the planet is highly eccentric at around 50%. The planet was discovered in La Silla Observatory on 30 June 2003 by Mayor, who used the CORALIE spectrograph. See also
