Sun and Moon Coincidence
5 Answers
How come that the apparent size of the sun and the moon are Exactly the same? Surely the odds of the one being 400 times further away and the other conveniently being exactly 400 times smaller are phenomenally illogical. What are the chances of this coincidence?

This is due to the physics of the situation. On average (so throughout it's obital period) the Moon is actually visually the same size as the Sun to the eye - although there are times when it is closer or further away and so does not match the size of the sun (remember that the Moon's orbit around the Earth is not a perfect circle). There is a mathematical / physics reason for it which I can't remember I'm afraid, but rest assured that it's not coincidence but is one of 'those things'.
