| Comet Tempel 1. Arrows a and b point to large, smooth regions. The impact site is indicated by the third large arrow. Small arrows highlight a scarp that is bright due to illumination angle, which shows the smooth area to be elevated above the extremely rough terrain. The scale bar is 1 km and the two arrows above the nucleus point to the sun and the rotational axis of the nucleus. Celestial north is near the rotational pole. Credit: NASA/JPL/UMd |
