Meteoroids & 2008TC3 : from space to Earth

Résumé :

Meteoroids are the most efficient way to deliver inter-planetary matter into Earth. I will show how the dynamics helps to understand how they are generated from comets. From recent studies it seems that cometary breakups is a major source, rather than regular outgasing process. In addition, the recent fall and recovery of 2008TC3 enables us for the first time to link a specific asteroid type (F) with a meteorite type (ureilite).
