The Largest Objects in the Asteroid Belt

A graphic showing the 22 largest objects in the asteroid belt by decreasing size, and roughly to scale, from 1 Ceres (diameter 940 km) to 7 Iris (diameter 214 km).

Four of those shown are direct images (two from orbit, two from Earth); the remainder are constructed from adaptive-optics images, optical light curves and shape models, as set out in the image footer.

All sources are also shown in the footer. If you use the graphic, make sure you credit the sources.

There are two detailed images from orbit [1, 4], two direct images from Earth [3, 624], 12 images constructed from adaptive-optics images and optical light curves [2, 7, 10, 15, 16, 31, 52, 65, 87, 324, 511, 704], and six shape models from light curves [19, 45, 48, 88, 451, 532].
