Webb5 mars 2024 · The brightest S-type asteroid, 7 Iris, is one of the brightest asteroids ever discovered. Most S-type asteroids are dominant in the inner part of the asteroid belt within 2.2 AU away from the Sun, and at 3 AU, they are still quite common. There are more than five sub-classes of S-type asteroids such as A-type, K-type, L-type, Q-type, and R-type. Webb1 nov. 2006 · The apparent size and shape of each asteroid was estimated after deconvolution using a new algorithm called AIDA. The mean diameter for the majority of asteroids is in good agreement with IRAS radiometric measurements, though for asteroids with a D < 200 km, it is underestimated on average by 6-8%.
Many Shapes and Sizes. Most asteroids are irregularly shaped, though a few are nearly spherical, and they are often pitted or cratered.
