HD 102195 b (also called ET-1) is an extrasolar planet orbiting the star HD 102195 in the constellation of Virgo, discovered in January 2006. It is the first planet discovered by the Exoplanet Tracker project, using a dispersed fixed-delay interferometer. The planet is an example of a hot Jupiter, and is likely to be a gas giant based on its mass.[1]
