About Mathilde
Discovered in 1885 by Johann Palisa. IAU designation: 253 Mathilde. Estimated diameter: 52.8 km. Absolute magnitude H: 10.35.
Visitado pela NEAR Shoemaker em junho 1997.
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.
