MARS:
- Diameter = 4,226 mi
- Distance from earth (as stated in the cited thingy) = 34,650,000 mi
- Diameter/distance ratio = 0.000122

MOON
- Diameter = 2,159 mi
- Distance from earth = 238,857 mi
- Diameter/distance ratio = 0.00904

Thus, Mars at 34.65M miles away, will look 1/74th (0.000122/0.00904) the size of the Moon.

simple math 34,650,000/238,857 = 145 (mars is 145 times further away than moon) 4226/2159 = 1.96 (mars almost 2 times a big) 145*1.96 = 73.98

so 34,650,000/238,857*1.96 means mars will look 74 times smaller than the moon

oh wait....both answers are the same, so you guys already knew that....

All this math is great. But have you guys factored in the Prime Quadruple into this analysis?
