Where Did The Asteroid That Killed the Dinosaurs Come From?

Welcome to The Snoozy Scientist, a calm corner of the universe where science, curiosity, and quiet storytelling come together 🌌✨ Sixty-six million years ago, a six-mile-wide asteroid struck Earth near what is now the Yucatán Peninsula, forming the Chicxulub crater and contributing to the extinction of roughly seventy-five percent of all species, including the non-avian dinosaurs. But the impact itself is only the final moment of a much longer cosmic journey. In this video, we gently trace that asteroid’s path backward through deep time. Where did it come from? Was it born in the asteroid belt between Mars and Jupiter? Nudged inward by gravitational resonance? Or shaped in a more distant, icy region of the early solar system? Through geological evidence, orbital mechanics, isotope analysis, and modern computer simulations, we explore how scientists reconstruct the origin of the rock that reshaped life on Earth. We examine the Yarkovsky effect, resonance gaps influenced by Jupiter, the characteristics of carbonaceous asteroids, and the clues preserved in iridium-rich boundary layers found across the globe. Along the way, we look at: • What near-Earth objects are and how we track them 🔭 • The difference between asteroids and comets • How orbital resonances send space rocks toward Earth • What impact debris reveals about composition and origin • Why this event happened sixty-six million years ago, and not earlier • How planetary instability in the early solar system still echoes today • Whether a similar impact could happen again This is not a story about sudden catastrophe alone. It is a story about slow gravitational nudges, millions of years of orbital drift, and the fragile intersection of timing and trajectory. It is about how a single event reshaped evolution, opening ecological space for mammals and, eventually, for us. Using the latest research in planetary science and asteroid dynamics, we follow the most supported origin theory for the Chicxulub impactor and explore the remaining uncertainties that keep scientists looking to the sky and back into ancient stone. If you enjoy calm, cinematic science documentaries about space, Earth’s history, mass extinctions, and the hidden mechanics of the universe, you’re in the right place 🌍🌠
