"The asteroid chip that became the recent meteorite came from a spot in the asteroid belt near Jupiter, about 2.5 times further from the sun than Earth is, according to NASA... At the University of Antioquia in Colombia, astronomers Jorge I. Zuluaga and Ignacio Ferrin produced a preliminary reconstruction of its orbit around the sun. It came from a well-known group of asteroids that frequently cross paths with Earth, known as the Apollo asteroids."

Looks like all those videos aided in calculating the trajectory.
