\mymulticolumn{2}{x{3.833cm}}{1. Crater formation starts with the impactor reaching the ground with a velocity of tens of kilometres per second. 2. The impactor penetrates into the surface by one or two diameters, compressing the rock ahead of it, before its momentum is lost. (milliseconds)  3. A very high pressure shock wave moves outwards, compressing the rock to very high pressures. (\textasciitilde{}seconds)  4. With the energy released, and the impactor completely vaporised, the rock around the impact site expands again, blowing vast amounts of debris out of the area in a spherical crater as the shock wave reflects backwards. (seconds-minutes)  5. Over longer time scales, re-expansion of the rock continues (sometimes lifting up a central peak), and the crater walls collapse, forming a larger, shallower crater. (minutes-hours)  6. Over geological time scales, erosion and sediment blur or bury craters.

\mymulticolumn{2}{x{3.833cm}}{Diverting the orbit of an object is technically possible, if we can predict a collision years or decades in advance. • For strong, solid objects (solid rock or metal), nuclear explosions could vaporise asteroid material and slightly alter the orbit, a few metres/second for every Megaton of explosion. • Rockets could be attached to the surface of an asteroid to push it, but thrusts would be very low. • Much harder for 'rubble piles': loosely bound collections of rocks, like 'Mathilde' – they would just disperse slightly, then clump back together under their own gravity. • Even if you could break up and disperse an object, it would be worse than doing nothing – it would spread the effects over a larger area. • \seqsplit{Diversionisessentiallyimpossiblefornewlyfoundcomets:} much higher velocities, very weak material, and less warning time (weeks to months).} \tn
