PROFESSOR RAPPAPORT | FUN FACT
Apparent Angular diameter
Ever wonder why the full moon and the sun look to be the same size when viewed from earth? The sun is approximately 400 times larger than the full moon, but it is also 400 times farther away. This results a one to one ratio and gives the apparent angular diameter equal to 1/2 a degree for both objects.
