# What would happen to the earth if the moon were to drift farther away from the planet?

The crest of spring and neap tidal waves, around New Moon and Full Moon days, would be lowered. The lunar disc would look smaller. The apparent magnitude will increase for the fainter moon.

#### Explanation:

The lunar tidal forces would become lesser in magnitude for the longer distance.

As of now, the apparent magnitude of Moon is $- 12.7$, compared to 0 for Vega. This would become $> - 12.7$. for the fainter Moon, at a farther distance. ...

For the brightest Sun, the apparent magnitude is $- 26.7$, nearly.

The apparent diameter would be lesser and the Moon would look smaller.
