Conference Summary: Meteoroids

  • Z. Ceplecha
Conference paper


Summarizing our meeting for its meteoroid part is mostly the task of definition, what meteoroids are. Some are certainly small pieces of comets as we know from meteor-stream comet associations. Jewitt in his invited talk draw our attention to definition of terms: asteroid and comet. It is certainly used as phenomenalistic description of the bodies, but it is also used in variance as denoting composition of the bodies. I heard the term “fireball” at least in three completely different meanings at this Conference. For me it is primarily a dazzling bright meteor in the Earth’s atmosphere: meteoric fireball. We should somehow redefine our terminology. Enormous progress in observing technics also brought asteroids to meteors and vice versa (I mean the phenomenalistic definition of these words). A new population of bodies in the 10-m size range was revealed. Some tell they are small extinct comets, may be building blocks of them, may come once a while in a form of giant comets into the inner solar system, some prefer origin by impacts of asteroids onto the terrestrial planets.
