About Astraea
Discovered in 1845 by Karl Hencke. IAU designation: 5 Astraea. Estimated diameter: 167 km. Absolute magnitude H: 6.96.
Quinto asteroide descoberto, depois de hiato de 38 anos.
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.
