The picture above is composed of four photos taken by NAVCAM attached to the Rosetta space probe. The images allow us to view the comet in high resolution and the odd shape of the comet stands out, which made it earn the nickname “rubber duck”.
The image resolution is 2.4 m/pixel and thus each original 1024 x 1024 pixel frame measures 2.5 km across.
