mass = >2.90 "M"JHD 196050 b is a 1378-day
extrasolar planet with aminimum mass of 2.90Jupiter mass . The averageorbital distance is 2.54astronomical unit s or 380gigameter s or 12.3microparsec s. Theeccentricity of the orbit is 22.8%. The periastron (closest) distance is 1.96 AU and the apastron (farthest) distance is 3.12 AU. The averageorbital velocity is 20.1 km/s and the semi-amplitude is 49.7 m/s. Thelongitude of periastron is 187° and thetime of periastron is 2,450,843 JD.The planet is typically discovered by using
Doppler spectrometer by looking for shifts in the spectrum of the star. InAustralia , Jones et al. found this planet in2002 by using thetelescope inAnglo-Australian Observatory .References
