| He studies small bodies in the solar system, including meteors, meteoroids and asteroids. |
| The basic purpose was to validate the hypothesis that the meteoroids were generated by fragmentation processes under violent conditions. |
| Given these evidences, we contend that there is a direct influence of ablating meteoroids on the topside of the mesospheric metal layer. |
| The distinction between asteroids and meteoroids having the same origin is culturally imposed and is basically one of size. |
| Asteroids and meteoroids are small pieces of rock that are debris left over from the formation of the solar system. |
| Rare meteoroids of masses exceeding 100 tonnes are not slowed appreciably by Earth's atmosphere and produce impact craters. |
