| 2091 Sampo | Discovered 1941 Apr. 26 by Y. Vaisala at Turku. |
| Named for the wonder-object in Kalevala, the Finnish national epic. Sampo was to produce every kind of fortune. When Kalevala and Pohjola (the North) were fighting for its possession, out at sea, it broke into pieces, and only tiny fragments could be found. |
