This week on Star Trails, we explore the fascinating world of space rocks—asteroids, comets, and meteors—and their impact on our planet and beyond. With recent talk of asteroid 2024 YR4 making headlines (don’t worry, it won’t hit us!), we break down what these celestial objects are, where they come from, and what makes them so important to study.We'll also take a look at the Tunguska and Chelyabinsk meteor events, the impact that wiped out the dinosaurs, and the Shoemaker-Levy 9 collision with Jupiter—real-life cosmic events that shaped our understanding of space hazards.Plus, we’ll check in on T Coronae Borealis, a star on the verge of a once-in-a-lifetime nova. And don’t forget to step outside and catch Mercury’s rare appearance on the western horizon this week, as well as a beautiful pairing of Venus and the crescent Moon.For more episodes and resources for backyard astronomers, visit www.startrails.show.
