(288 ) Glauce is an asteroid of the main asteroid belt, which was discovered on 20 February 1890 by Karl Theodor Robert Luther at the observatory Dusseldorf.

It was named after celestial bodies Glauce, a subsidiary of Corinthian King Creon and wife of Jason in Greek mythology.

Glauce moves at a distance of 2.1757 ( perihelion ) to 3.3370 ( aphelion ) astronomical units in 4.5762 years of the sun. The orbit is inclined 4.3294 ° to the ecliptic, the orbital eccentricity is 0.2107.

Glauce has a diameter of 32 kilometers. It has a bright silicate- rich surface with an albedo of 0.197. In 50 days it rotates around its own axis and thus has one of the lowest rotational periods of the known celestial bodies in the solar system. Only the planets Mercury and Venus rotate slowly on their axes. Glauce leads in their rotation probably a tumbling motion, similar to the asteroid Toutatis.
