Glauke is asteroid #288 and also known as A890 DA. Glauke is a very slow rotator and probably tumbling. Glauke’s orbit is characterized by a semi-major axis of 2.76 Astronomical Units, an eccentricity of 0.21, a period of revolution of 1 671 days, and an inclination of 4.3 degrees. Glauke is the last of the asteroid discoveries of the German astronomer Robert Luther. Glauke was discovered at the Düsseldorf-Bilk Observatory.

Glauke is named after Princess Glaúkē (Γλαύκη) from Greek mythology. She is also known as Kreousa (Κρέουσα). She is the daughter of King Kréōn (Κρέων) of Corinth. This king promised her to the hero Jason, after whom the asteroid Jason is named. Jason at that time already was married to Medea, after whom the asteroid Medea is named. So Jason abandoned Medea for Glaúkē (Γλαύκη). Medea took revenge and cursed a dress (or a crown) and gifted this item to Glaúkē (Γλαύκη). As soon as she put it on, she couldn’t put it off and it began to burn her body. Her father came to her rescue, but this resulted only in both of them burning to death. Glaúkē (Γλαύκη) shall also have jumped into a well in the hope to quench the fire this way.

Glaúkē (Γλαύκη) means “blue-gray”, while Kreousa (Κρέουσα) simply shall mean “princess”. So Kreousa (Κρέουσα) isn’t necessarily a name and “blue-gray” hence is the only candidate for being her name. Glauke hence is another asteroid of color. Glauke also represents women, who suffer from the actions of a rival.
