Question:
If I am standing on the Equator, and a star is rising on the eastern horizon, how much atmosphere would I be looking through?


Replies:
Dear Tim,

A lot! I remember when we were observing, when the telescope was close to the horizon it would tell us that we were looking through 8 times the amount of air as when we look overhead. So the answer is at least 8.
