Steins: A diamond in the sky
6 September 2008
| An animation of the closest approach of Rosetta to asteroid Steins, taken with the OSIRIS imaging system’s Wide Angle Camera. The image sequence starts 3 minutes before closest approach, from a distance of about 2000 km and ends 4 minutes after closest approach. At the start of the animation, the sun illuminated the asteroid from behind the spacecraft and no shadows are visible on the its surface. Later, the sunlight is incident from the left, and craters and more surface features become visible.

| | | | | Asteroid Steins seen from a distance of 800 km, taken by the OSIRIS imaging system from two different perspectives. The effective diameter of the asteroid is 5 km, approximately as predicted. At the top of the asteroid (as shown in this image), a large crater, approximately 1.5-km in size, can be seen. Scientists were amazed that the asteroid survived the impact that was responsible for the crater.
