34. It's the opposite for our moon.

Due to tidal forces with the oceans, the moon is moving away from us. About four centimeters per year. It could eventually stabilize or escape our orbit. But by the time that’d happen, the sun will be all done.

Our lunar buddy will be with us til the end.

Edit: when it first formed, the moon was much, much, much closer to earth. Like ten hour orbits. That must’ve been hell in the oceans. The tides would’ve been daily tidal waves.
