249 Ilse is a Main belt asteroid. It has an unusually slow rotation period, about 3.5 days.
It was discovered by C. H. F. Peters on August 16, 1885 in Clinton, New York and was named after Ilse, a legendary German princess.
Due to the long rotation period, a possible asteroidal satellite of Ilse was proposed by R. P. Binzel in 1987 however no evidence of this has been found.
Ilse is a common female name, technically a German diminutive of Elisabeth, functioning as a name in its own right chiefly in Austria, Belgium, Germany, the Netherlands, Switzerland and all of the Scandinavian countries including Finland. It may refer to:
Ilse (Bega) is a river of North Rhine-Westphalia, Germany.
Coordinates: 52°01′29″N 8°49′55″E / 52.02472°N 8.83194°E / 52.02472; 8.83194
The Ilse is a river that rises at about 900 metres (3,000 ft) above sea level on the northern slopes of the Brocken. During its first few kilometres it flows as a narrow brook, almost invisible to the observer, down the side of the Brocken. Known here as the Verdeckte Ilse ("hidden Ilse") it gurgles its way under blocks of granite that hide the stream bed from above.
The Ilse then rushes through the narrow Ilse valley, hemmed in to the east by the rugged, cross-topped Ilsestein, passes by Ilsenburg into the Harz Foreland, flows through Veckenstedt, Wasserleben, Osterwieck and Hornburg and discharges into the Oker near Börßum together with the Schiffgraben from the Großes Bruch. Its total length is around 40 kilometres (25 mi).
Local folklore personifies the river as the beautiful Princess Ilse, who has her home in the rocks of the Ilsestein. The Ilse is mentioned in literary works such as the Harzreise ("Harz Journey") by Heinrich Heine.
This bloodshot blur, it will not pass
