Ian GriffinIn 1609, German astronomer Johannes Kepler published what became known as his first two laws of planetary motion. A consequence of this is that a planet’s distance from the sun varies with time. In Earth's case, our closest approach (astronomers call this low point the perihelion) took place in January. The difference between Earth's perihelion and aphelion distance is approximately 3%. I decided to try to record the difference in solar size by taking pictures of the sun at aphelion and perihelion.
