Template:Minor Planet 17 Thetis (thee'-təs (key)) is a large Main belt asteroid. It is a S-type asteroid, so it has a relatively bright silicate surface.
It was discovered by R. Luther on April 17, 1852. It was his first asteroid discovery. Its name comes from Thetis, the mother of Achilles in Greek mythology.
One Thetidian stellar occultation was observed from Oregon in 1999. However, the event was not timed.
