That we have a reason to invent the word 'eclipse' bothers you?

No Hitch1978, I am not bother that we had to invent a word to describe one celestial object passing in front of another celestial object. I'm bothered by the fact that during a typical solar eclipse observed on from the earth, the moon exactly covers the sun.

I apologise.

I am clearly misunderstanding something, could you please define the word 'exactly' as used in your post.
