We do not see lunar eclipses every time the Moon is full because: the Moon is usually on the wrong side of the Earth to be seen. the Moon's orbit is tilted relative to the Earth's orbit around the Sun. sometimes lunar eclipses occur when the Moon is in a different phase. the Moon often produces so m ...

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.
