The Greek mathematician and astronomer Eratosthenes is credited for calculating the Earth's circumference around 240 BC. He did so by comparing the angle of the shadow cast by a vertical stick at noon in two different cities and using basic trigonometry to estimate the Earth's size.

What mathematical equation would you use to explain why the sun and the moon appear to be the same size?
The apparent size of an object can be calculated using the equation: apparent size = actual size / distance between observer and object. The sun and the moon appear to be the same size in the sky because even though the sun is much larger than the moon, it is also much farther away from Earth, resulting in them having a similar apparent size when viewed from Earth.
