Seagate,
The moon is closer enough and yet it does not glare when you approach it?

Glare is a whole different thing already. Like most people point out earlier the Albedo number of the moon surface is very low, so the light reflected is not enough to produce glare that you commonly see from bright light source or the sun, but at the same time the reflected light is bright enough to partially illuminate Earth. The moon does get brighter the closer you are to it, as experienced by Astronauts on Apollo missions. Picture and video of moon landing you see in general media has been edited to give it a better constrast.

Let's do a thought mathematics, assuming from the sun is 100%, by the time it hits the moon, maybe 10% is left, add in the Albedo factor, maybe 1% get reflected, and that 1% get scattered and by the time it reaches the earth, passing through the atmosphere which further scatter the light, only a tiny fraction of what the sun emitted is left.

Try this if you still have doubt

Items needed :

- 1 slightly dull metallic surface (the moon)
- 1 laser pointer (the sun)
- Your pair of eyes (the earth), or a wall.

Shine the laser on the reflecting surface, and you can still see the red dot on the surface(albeit duller), the visible dot is actually reflected light off the reflector going into your eyes. If you bring the reflecting object close enough to the wall, you can see a feint red dot on the wall(the moonlight).

You can replace the dull reflector with a mirror, to simulate the difference between a high and low Albedo number. Remember the surface of the moon has a low Albedo number.
