288 Glauke

It was discovered on 20 February 1890, by Robert Luther at Düsseldorf-Bilk Observatory in Germany.

It is named after Creusa (known as Glauce or Glauke), a daughter of Creon, a king of Corinth in Greek mythology.

[3] Glauke has an exceptionally slow rotation period of about 1200 hours (50 days).

The rotation is believed to be "tumbling", similar to the near-Earth asteroid 4179 Toutatis.

It is a common, stony S-type asteroid in both the Tholen and SMASS classification.
