Early Life

After his father died, Copernicus was supported by his maternal uncle, Lucas Watzenrode, who helped guide his education.

Chapter 2

A Big Question

Construct a mathematical model of the planets that was simpler and more coherent than the inherited Earth-centered system.

What Happened

He placed the Sun near the center and treated Earth as a moving planet, reorganizing the geometry of the Solar System.

Chapter 4

Why It Matters

The heliocentric model changed astronomy’s basic frame of reference and opened the path to Kepler, Galileo, and Newton.
