What You Would Experience Riding Apophis Past Earth in 2029

What will you actually experience when the massive asteroid Apophis passes closer to Earth than our own weather satellites in 2029? We leave the safety of the ground to take a quiet journey on the surface of this ancient rubble pile as it glides silently past our world. Tonight, we'll explore the real physics of this historic close encounter. You'll discover how Earth's gravity will trigger silent quakes across the asteroid's surface, the gentle thermal forces that made its orbit hard to predict, and how this brief flyby will permanently alter the rock's path—all while keeping our planet entirely safe.
