| Meteors, Asteroids and Comets |

| Scientists from the California Institute of Technology (Caltech), Southwest Research Institute® (SwRI®), and Charles University in the Czech Republic have shown that the breakup of the 100-mile-wide asteroid called Veritas blanketed the Earth with an exceptionally large volume of extraterrestrial dust. Using computer models to track the orbits of the asteroid fragments backwards in time, they found that 8.2 million years ago, all of its fragments shared the same orbital orientation in space. This event coincides with a spike in interplanetary dust in seafloor sediments. |
