About Irma
IAU designation: 177 Irma. Estimated diameter: 40.69 km. Absolute magnitude H: 9.63.
Asteroide 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.
