For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

16525 Shumarinaiko | Discovered 1991 Feb. 14 by K. Endate and K. Watanabe at Kitami. |
Lake Shumarinai is located in the western part of the Nayoro basin. It was created artificially in 1943 by damming the River Uryuu for irrigation and the generation of hydraulic electricity. As one of the prefectural natural parks, the lake is well known for its beautiful scenery. |
