Summary

edit
Description
English: Lightness-reversed cropped plot of orbits of all the known Potentially Hazardous Asteroids (PHAs), numbering over 1,400 as of early 2013. These are the asteroids considered hazardous because they are fairly large (at least 460 feet or 140 meters in size), and because they follow orbits that pass close to the Earth's orbit (within 4.7 million miles or 7.5 million kilometers).
Español: Trayectorias orbitales en reversa de los 1400 Asteroides Potencialmente Peligrosos (PHAs) conocidos a principios de 2013, y que son considerados problemáticos debido a su tamaño (al menos 140 metros de diámetro), y porque siguen órbitas cercanas a la órbita terrestre (acercamiento de 7.5 millones de kilómetros o menos).
