The Amazing Mystery of the Moon

[Speedskater]

The apparent size of the moon is in fact getting smaller! The moon is slowly drifting away from the Earth. Don't remember the number but it may be something like a centimeter a year (or maybe a century). In a billion or three years it will leave Earth's orbit. But by then the Sun will be on it's way to being a giant red star so nobody will worry about the moon leaving.

 

I looked it up:

The Moon is spiraling away from the Earth at an average rate of 3.8 cm (1.5 in) per year
