This single frame Rosetta navigation camera image of Comet 67P/Churyumov-Gerasimenko was taken on 22 August 2015 from a distance of 336 km from the comet centre. The image has a resolution of 28.6 m/pixel and measures 29.3 km across.
The comet reached the closest point to the Sun along its 6.5-year orbit, or perihelion, on 13 August 2015. The comet’s activity, at its peak intensity around perihelion and in the weeks that follow, is clearly visible in the image, including a significant outburst.
The original image and more information is available on the blog: CometWatch 22 August
