... Lunar eclipse- occurs when the moon, always a full moon, passes through the shadow of Earth. Earth blocks the sun’s light from reaching the moon, but the moon does not look black. Instead, it looks red. This is because the Earth’s atmosphere bends the red light, which then reflects off the moon. Ref ...

... He used geometry and proportions to estimate the relative distances between the Sun, Earth and Moon. Once he had these, he used the eclipses to state that the Sun and Moon had the same angular size, so their relative sizes could be estimated in proportion to their relative distances.

Astronomical unit

The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun. However, that distance varies as the Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year. Originally conceived as the average of Earth's aphelion and perihelion, it is now defined as exactly 7011149597870700000♠149597870700 meters (about 150 million kilometers, or 93 million miles). The astronomical unit is used primarily as a convenient yardstick for measuring distances within the Solar System or around other stars. However, it is also a fundamental component in the definition of another unit of astronomical length, the parsec.
