About Itokawa
Discovered in 1998 by LINEAR. IAU designation: 25143 Itokawa. Estimated diameter: 0.33 km. Absolute magnitude H: 19.26.
Visitado por Hayabusa (JAXA) que retornou amostras a Terra em 2010.
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.
