Comet 67P/C-G on 17 September from 1.9 km - OSIRIS NAC
This image from Rosetta's OSIRIS narrow-angle camera captures an intriguing boulder with a very flat face, close to the bottom of the scene.
The spacecraft's trajectory around the comet changed progressively during the final two months, bringing it closer and closer to the comet at its nearest point along elliptical orbits. This image was taken on 17 September 2016 by Rosetta's OSIRIS narrow-angle camera on the spacecraft's fourteenth ellipse, from a distance of 1.9 km from the surface. The image scale is about 3.5 cm/pixel at the centre of the image.
