In "A Short History of Nearly Everything," Bill Bryson shares fascinating insights about asteroids and their vast distances from one another. He emphasizes that, on average, an asteroid is approximately one and a half million kilometers away from its closest neighbor. This remarkable fact highlights the emptiness of space and the relative isolation of these celestial bodies.

This distance underlines the scale of our solar system and the challenges of understanding and exploring it. Bryson's work encourages readers to appreciate the complexities of astronomy and the marvels of the universe surrounding us, while also emphasizing how much uncertainty remains in our knowledge of such distant objects.
