| Spectral class 5 | SApproximately 17% of all known asteroids are of an S-type (for stony composition. S-types are moderately bright (with an albedo of 0. 22) and consist of metallic nickel- iron mixed with iron- and magnesium- silicates. They dominate the inner to central ma |
| 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 | 8.79 |
| 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 | 0.138 |

172 Baucis is a fairly 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 composition is a mixture of rocks and metallic iron- nickel.
It was discovered by Alphonse Borrelly on February 5, 1877 and named after a character in the Greek legend of Baucis and Philemon.
