About Parthenope
Discovered in 1850 by Annibale de Gasparis. IAU designation: 11 Parthenope. Estimated diameter: 153.3 km. Absolute magnitude H: 6.73.
Asteroide tipo S do cinturao principal.
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.
