We are fortunate that was not a comet, but a used up Russian rocket stage, that reentered the Earth's atmosphere above Mexico, if this is a recent shot. Comets could be tens of km and if that would hit, humanity could be wiped out actually. Luckily, chances are very small this will hit, but the dinosaurs will actually get angry with you saying that, so watch out!
