The $100 Quintillion Asteroid

A book-club-adjacent talk at Woodson Regional, this one ties into the 2026 One Book, One Chicago season (*Orbital* by Samantha Harvey) but focuses on real science instead of fiction. Adler Planetarium astronomer Geza Gyuk leads a Tuesday evening session, September 15 from 6:00 to 7:00 PM, covering how astronomers study asteroids, assess the threat they pose to Earth, and what they reveal about our solar system’s origins.
