Question

why do we not experience a lunar and solar eclipse every month?
because the moons orbital plane is tilted at 5° and the earth, moon, and sun are not always lined up perfectly
because the earths axis is tilted 23.5° and we cant always see them from our location
because the distance of earth varies from the sun during its orbit
because the distance of the moon varies from earth during its orbit

Explanation:

Lunar and solar eclipses occur when the Earth, Moon, and Sun are aligned. The Moon's orbital plane is tilted at about \(5^{\circ}\) relative to the Earth - Sun plane. This tilt means that perfect alignment (for an eclipse) doesn't happen every month.

Answer:

Because the Moon's orbital plane is tilted at \(5^{\circ}\) and the Earth, Moon, and Sun are not always lined up perfectly.
