| Spectral class | CC-type asteroids are carbonaceous asteroids. They form 75% of known asteroids, and are extremely dark ( albedo 0. 03), similar to carbonaceous chondrite meteorites (types CI and CM). They dominate the outer belt beyond 2. These asteroids have approximatel |
| Abs. magnitudeIn astronomy, absolute magnitude is the apparent magnitude, m an object would have if it were at a standardized distance away. It allows the overall brightnesses of objects to be compared without regards to distance. Absolute Magnitude for stars M In stel | 8.13 |
| AlbedoNote: This article discusses the physical or planetological property of albedo. For other usage, see Albedo (disambiguation). The albedo is a measure of reflectivity of a surface or body. It is the ratio of electromagnetic radiation reflected to the amoun 4 | 0.043 |

145 Adeona is a rather large Main belt asteroidAn asteroid is a small, solid object in our Solar System, orbiting the Sun. An asteroid is an example of a minor planet (or planetoid , which are much smaller than planets. The asteroids are believed to be remnants of the protoplanetary disc which were no. Its surface is very dark, and composition likely of primitive carbonates.
The Adeona family of asteroids is named after it.
It was discovered by C. H. F. Peters on June 3, 1875 and named after Adeona, a protector of children in Roman mythology.
Adeona has been seen occulting a star once ( July 9, 2002).
