By the Inverse Square Law:
Which states that the energy we receive is inversely proportional to the square of the distance , therefore,
2^2 = 4 times as dim.
10^2 = 100 times as dim.
1/3^2 = 9 times as bright.

Using the inverse square law:
1) a quarter the brighness (4 times fainter).
1) 1% the brightness (100 times fainter).
3) 9 times brighter.

Brightness is inversely proportional to the square of the distance.
So if you move a star twice as far away, it will be 1/4 as bright.
And if you move it 3 times closer it will be 9 times brighter.
