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.
This graphic is for non-commercial use only. Image sources are shown in the footer.

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].
