The spectral energy distribution at millimetric wavelengths of planets is an important benchmark to inter-calibrate different CMB experiments and a source of information on the atmospheric structure of planets. Planck/LFI observed Mars, Jupiter, Saturn, Uranus and Neptune from three to eight times during its mission. In particular, as a calibrator Jupiter allows accurate comparison due to its high S/N ratio. Since planets are moving objects, the measure must account for their proper motion as well as a number of second order effects. Here we present the results of accurate measurements of brightness temperature Tb of planets, and we compare them with WMAP.
