What would have to happen for lunar and solar eclipses to occur every month?
First, you have to understand that the Moon has a tilt in its orbit. Its tilt is large enough to miss the Earth’s shadow or the Sun’s main stream of light. The Moon has to remove its orbital tilt for solar and lunar eclipses to happen every month. But eventually, the Moon will be far enough that it does not block enough sunlight for a solar eclipse to occur (this is because the moon is moving away from Earth because it orbits the Earth slower than the Earth rotates).
