What Would Happen If A Needle Hit Earth At Almost The Speed Of Light?

A steel sewing needle weighing a tenth of a gram, arriving at 99.9% of the speed of light, carries about 190 trillion joules of energy of motion, the same as roughly 46,000 tonnes of TNT, or three Hiroshima bombs. It would not reach the ground: the air cannot get out of its way, so it would burst high in the sky as a cloud of superheated gas and radiation, like the 2013 Chelyabinsk meteor at a tenth of the power.
