What is a tholus? A tholus is a type of small mountain. These images show such a feature on dwarf planet Ceres called Kwanzaa Tholus. Kwanzaa, meaning "first fruits" in Swahili, is an African-American festival based on ancient African harvest celebrations, and takes place each year from December 26 to January 1.
Kwanzaa Tholus measures about 22 by 12 miles (35 by 19 kilometers) and is elevated about 2 miles (3 km) above its surroundings. Because the mountain does not rise sharply above the ground, it is difficult to see in the mosaic on the left, although a small crescent-shaped shadow stands out. The image on the right, which is an elevation map of the area, shows where Kwanzaa Tholus is more prominently.
