Recently scientists have found that the asteroid that wiped out the dinosaurs( 60 million years ago) hit at ‘deadliest possible’ angle(40-60). Identify the asteroid?

The city-size asteroid that hit Earth 66 million years ago and doomed the dinosaurs to extinction came from the northeast at a steep angle, maximizing the amount of climate-changing gases unleashed into the atmosphere, a new study has found. That the 200 kilometer (125 mile) wide Chicxulub crater in present-day Mexico was formed when the asteroid struck, ultimately killing off three-quarters of life on the planet, is a fact most scientists agree on. But the trajectory and direction of that impact is still a topic of debate.
