About Thetis
Discovered in 1852 by Robert Luther. IAU designation: 17 Thetis. Estimated diameter: 90 km. Absolute magnitude H: 7.92.
Asteroide tipo S do cinturao interno.
Limitation
Osculating elements are from epoch 2461000.5 JD. Keplerian propagation ignores perturbations (especially Jupiter for belt asteroids). For precision beyond months, consult JPL Horizons.
