A screen cap from a film condensing the discoveries of the more than 530,000 asteroids known by 2010 into a little more than 3 minutes. As each asteroid is discovered it flashes white: those that pose no threat of hitting Earth turn green while those that pass close to Earth turn yellow. The red ones, though, cross Earth’s orbit - they’re the ones to worry about. The Sun is the yellow dot in the middle; Earth is the blue-green dot above and to the right of the Sun, about halfway between it and the vivid green circle of the main asteroid belt.See the film here: http://www.datapointed.net/2010/09/asteroid-discovery-animation/
