Context. Imaged in the gap of a transition disk and found at a separation of about 195 mas (similar to 22 au) from its host star at a position angle of about 155 degrees, PDS 70 b is the most robustly detected young planet to date. This system is therefore a unique laboratory for characterizing the properties of young planetary systems at the stage of their formation.
