Rosetta image of the Moon

This image of the Moon was taken with by Rosetta's OSIRIS Narrow Angle Camera (NAC) at 07:36 CET on 13 November 2007, about nine hours after Rosetta's closest approach to Earth during one of its gravity assist manoeuvres.

OSIRIS has been designed to image faint objects, so a neutral density filter was placed in the optical path to reduce the sensitivity of the camera to one fiftieth. The above image was acquired through the far-focus red filter of the camera (750 nanometres).
