About Apophis
Discovered in 2004 by Roy Tucker / David Tholen / Fabrizio Bernardi. IAU designation: 99942 Apophis. Estimated diameter: 0.34 km. Absolute magnitude H: 19.09.
Vai passar a 31000 km da Terra em 13 abril 2029 (mais proximo que satelites geoestacionarios).
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.
