We report the detection of the first extrasolar planet, ET-1 (HD 102195b),using the Exoplanet Tracker (ET), a new generation Doppler instrument. Theplanet orbits HD 102195, a young star with solar metallicity that may be partof the local association. The planet imparts radial velocity variability to thestar with a semiamplitude of $63.4\pm2.0$ m s$^{-1}$ and a period of 4.11 days.The planetary minimum mass ($m \sin i$) is $0.488\pm0.015$ $M_J$.Comment: 42 pages, 11 figures and 5 tables, Accepted for publication in Ap
