| 188847 Rhipeus | Discovered 2006 Mar. 23 by Calvin College at the Calvin-Rehoboth Observatory. |
| According to Virgil, Rhipeus died fighting alongside Aeneas in the fall of Troy. The poet says that Rhipeus was "the single most just man among the Trojans and the best preserver of fairness, but the gods thought otherwise". In the Paradiso, Dante places him in the sphere of Jupiter in the eye of the eagle. |
