The relative sizes of each asteroid are also illustrated.<\/p>\n<p>All main-belt asteroids and Trojan asteroids with orbits known to high precision are shown. The animation is rendered with a timestep of 3 days.<br \/>\nThe compositional gradient of the asteroid belt is clearly visible, with <strong><span style=\"color: #99cc00;\">green Vesta-family<\/span><\/strong> members in the inner belt fading through the <strong><span style=\"color: #0000ff;\">blue C-class asteroids<\/span><\/strong> in the outer belt, and the <strong><span style=\"color: #993366;\">deep red<\/span> <span style=\"color: #993366;\">Trojan swarms<\/span><\/strong> beyond that.<\/p>\n<p>Occasional diagonal slashes that appear in the animation are the SDSS survey beams; these appear because the animation is rendered at near the survey epoch.<\/p>\n<p>The average orbital distances of Mercury, Venus, Earth, Mars, and Jupiter are illustrated with rings.<\/p>\n<p>Colors represented with the same scheme as Parker et al.
