Rosetta comet images with scalebar

7 August 2014 in Astronomy

I have seen several images of the comet “67P/Churyumov-Gerasimenko” in the last days but curiously no-one made an image with a clear scalebar. Here I prepared 4 of them using images from here.

Comet 67P, 3 August, 285 km — Image taken on the 3rd of August from 285 km.

Comet 67P, 3 August, 285 km — Image taken on the 3rd of August from 285 km.

Comet 67P, 6 August, 120 km — Image taken on the 6th of August from 120 km: “the image shows the comet’s ‘head’ at the left of the frame, which is casting shadow onto the ‘neck’ and ‘body’ to the right.”

Comet 67P, 6 August, 130 km — Image taken on the 6th of August from 130 km: “the image shows a range of features, including boulders, craters and steep cliffs.”
