Instagram favs - Putting Rosetta's recent 1500 km 'far' excursion into perspective with a ground based image taken on 30 September 2015 with the Liverpool Telescope. One dot represents the comet centre, the other Rosetta,1500 km away but still well inside the coma! The comet's tail streams out to the right of this image (visible in wider images).
