New perspectives – CometWatch 6 February

Today’s CometWatch entry presents the NAVCAM’s first single frame image capturing the entire comet nucleus since leaving bound orbits last week. The image was taken on 6 February from a distance of 124 km to the centre...

According to recent model calculations, the southern half of Comet 67P/C-G (right image)  could lose a dust layer of up to 20 metres during one orbit. Due to the seasonal cycle of the comet, the northern half (left and centre images) is much less subject to erosion.
