11. Eclipses
An eclipse occurs when the Earth, Moon, and Sun are in a straight line. Solar eclipses happen when there is a new Moon, between the Sun and Earth. During a Full Moon, a lunar eclipse occurs, and that is when the Earth is between the Moon and the Sun.
The Moon orbits around the Earth at an incline so an eclipse will not occur every time there is a Full or New Moon. The Moon has to be near the intersection of the Sun and Moon’s orbital planes in order for us to see an eclipse. Roughly every 18 years an eclipse of the Sun by the Moon and the Moon by the Earth happens.
