How to calculate the distance to the Sun.

We have all wondered at least once how does the universe look like, how does the moon look like, how does the sun look like and how do all the galaxies in our gigantic universe look like. Let me show you a simple thing that I have learned during my high-school studies. HOW TO CALCULATE THE DISTANCE TO THE SUN!

Tape a small coin like a dime to a window and view it with one eye so that it just blocks out the full sun. This occurs when your eye is about 110 coin diameters away. Then the ratio of coin diameter/ coin distance is about 1/110. Geometrical reasoning of similar triangles show this is also the ratio of sun diameter/ sun distance. So the distance to the sun is 110 times the moon’s diameter.
