Comet 103P/Hartley 2 was the target of the EPOXI mission. Remote observations from France and India, of the scattered light properties (and mainly its linear polarization) allowed us to determine an evolution of the physical properties of the dust particles in the coma. The properties displayed seem similar to those of other Jupiter Family comets (JFC).
