Abstract
We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a young star with solar metallicity that may be part of the local association. The planet imparts radial velocity variability to the star with a semiamplitude of 63.42.0 m s-1 and a period of 4.11 days. The planetary minimum mass (m i) is 0.4880.015 MJ.
