Wiping out the Moon would certainly have some good, bad and ugly consequences straight away, but hardly apocalyptic. The biggest impact would take time to manifest: destabilising the Earth’s rotation. Today, Earth’s axis is tilted at 23.4° with respect to our orbit around the Sun. But there is a slight wobble in this spin cycle. The wobble is like the one you see with a spinning top, slowly making the tip trace a circle as the toy spins rapidly around. For the Earth, it’s a rather slow wobble, taking around 26,000 years to go full circle. It’s also quite gentle, moving the Earth’s axis by just 2.4 degrees. But without the Moon to stabilise it, this wobble would become erratic and extreme.
Sometimes, the Earth’s axis would point straight up and down at right angles to the Earth’s orbit of the Sun. In this scenario, seasons would be a thing of the past, and night and day would be equally long all year round. At other times, the Earth would tilt all the way over and lie on its side in relation to its orbit around the Sun. This would mean the poles would be burning hot and the equator freezing cold.
In effect, removing the Moon would spell extreme climate change. There would be huge differences between temperatures and daylight throughout the year, and ice ages would hit different parts of the world every few thousand years. Lucky for us then that the Moon is going nowhere any time soon.
