Luna is very special, you see. Although every part of her body is proportional to the rest of her, her eyes are the size of the moon.

I plan to calculate all sorts of silly things about Luna.

When calculating, I will follow a few guidelines.

I will use any piece of information about our universe, generally with a link to where I got the information. Since this is just for fun, I will choose reader accessibility over rigor when looking for sources, but avoid using anything too particularly sketchy.

I’ll also have to make up information about Luna just to have a reference for some calculations. I’ll keep a running list of these assumptions on a separate page. When displaying the results of calculations, I’ll use the rules of significant figures. Of course *unrounded* values will be used in further calculations, not the number displayed in significant figures. Anything I’ve calculated once, I won’t bother recalculating in later posts unless I have a good reason.

Something that might come up often is the proportion of the Moon’s diameter (3.4762*10^{6} meters, using the equatorial radius) to the diameter of the human eye (24 millimeters, or 2.4*10^{-2} meters). I’ll call this proportion the Lunar Scale Factor:

\( \large \Lambda = \frac{3.4762*10^{6} meters}{2.4*10^{-2} meters} = 1.5*10^{8} \)
