The earths gravitational pull keeps the moon orbiting around and from straying away from it and into the vast expanses of outer space.
-- 400 nm shifted to 430 nm . . . longer than it should be; "red shifted"; moving away from Earth
-- 610 nm shifted to 580 nm . . . shorter than at source; "blue shifted"; moving toward Earth
-- 512 nm shifted to 480 nm . . . shorter than at source; moving toward Earth
-- 670 nm shifted to 690 nm . . .longer than at source; moving away from Earth
Now I'd just like to ask one more itty bitty question, that you can think about while you're on this subject: Astronomers really do this.
