About Kalliope
Discovered in 1852 by John Russell Hind. IAU designation: 22 Kalliope. Estimated diameter: 167.5 km. Absolute magnitude H: 6.79.
Asteroide binario tipo M com sua lua Linus.
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.
