P3_10 Extinction Event

Kate Houghton, Ashley Clark, Henry Simms, Jacek Kuzemczak



This article calculates the dimensions of the crater that triggered the series of events leading to the extinction of the dinosaurs. The diameter of a crater due to an asteroid traveling at escape velocity was calculated to be 71.2 km. An incoming velocity estimate of 54.2 kms-1 was made and the crater depth is estimated to be 4.00 km using Newton's projectile penetration depth approximation.
