Themisto
Themisto A small satellite of Jupiter, distance 7 284 000 km; also known as Jupiter XVIII. It orbits every 130.0 days and is about 8 km in diameter. Themisto was first seen in 1975 but not confirmed until 2000, in both cases from ground‐based observations. It gives its name to the Themisto prograde irregular group of Jovian satellites, of which it is so far the sole member.
