The Planck satellite represents the most precise thermometer ever built up to now. Thanks to its accuracy, in the next future Planck will provide fundamental information on our primordial Universe. After a review of the Planck scientific goals, I will concentrate on its working principle and the on-board instrumentation. I will then talk about its measurements giving few preliminary results.
