Four-image montage comprising images taken by Rosetta’s navigation camera from a distance of 9.7 km from the centre of comet 67P/C-G – about 7.7 km from the surface. The corresponding image scale is about 65 cm/pixel, so each 1024 x 1024 pixel frame is about 665 m across.
The individual image frames and more information is available via the blog: CometWatch – 28 October
