Preface: A long-awaited asteroid sample has landed in the US, said CNN – https://edition.cnn.com/2023/09/24/world/osiris-rex-asteroid-sample-return-scn/index.html

Background: Asteroid 101955 Bennu – Level 3 on the Palermo impact hazard index, a small celestial body with the highest risk of impacting the Earth.

Early in the history of the solar system, the gravity of newly formed Jupiter brought an end to the formation of planetary bodies in this region and caused the small bodies to collide with one another, fragmenting them into the asteroids we observe today.

the slight push created when the asteroid absorbs sunlight and re-emits that energy as heat — and gravitational tugs from other celestial bodies, it has drifted closer and closer to Earth from its likely birthplace: the Main Asteroid Belt between Mars and Jupiter.

Why does NASA track it?

Chicxulub crater, the buried remnants of an asteroid impact off the Yucatán Peninsula in Mexico that killed off the dinosaurs 66 million years ago.
