- Source: A-type asteroid
A-type asteroids are relatively uncommon inner-belt asteroids that have a strong, broad 1 μm olivine feature and a very reddish spectrum shortwards of 0.7 μm. They are thought to come from the completely differentiated mantle of an asteroid, and appear to have a high density. One survey found that 7 similar A-, V- and X-type asteroids had an average density of 3.6 g/cm3.

A-type asteroids are so rare that as of August 2024, only 17 had been discovered:
