(288) Glauke is an asteroid of the main asteroid belt that was discovered on February 20, 1890 by Karl Theodor Robert Luther at the Düsseldorf observatory .
The celestial body was named after Glauke , a daughter of the Corinthian king Creon and wife of Jason from Greek mythology .
Glauke moves at a distance of 2.1757 ( perihelion ) to 3.3370 ( aphelion ) astronomical units in 4.5762 years around the sun . The orbit is inclined 4.3294 ° to the ecliptic , the orbital eccentricity is 0.2107.
Glauke has a diameter of 32 kilometers. It has a light, silicate-rich surface with an albedo of 0.197. In 50 days it rotates around its own axis and thus has one of the smallest periods of rotation of the known celestial bodies in the solar system . Only the planets Mercury and Venus rotate more slowly around their axes. Glauke is likely to make a tumbling motion as it rotates, similar to the asteroid Toutatis .
