    204 Kallisto is a fairly typical, although sizeable Main belt asteroid. It is classified as an S-type asteroid. Like other asteroids of its type, it is light in colour.

    It was discovered by Johann Palisa on October 8, 1879, in Pola.

    The asteroid was named after the same nymph Callisto in Greek mythology as Jupiter's moon Callisto.
