When the light ftom a star is observed at wavelengths shorter than they SHOULD BE, that indicates that the star is moving toward Earth. The wavengths don't shift while you're watching them. They're constant, at a wavelength shorter than they should be. The trick is how to know what the wavelengths of the light you're watching should be.

On your first attempt you leave the surface of the earth at v = 5534 m/s. how far from the center of the earth will you get?
Tamiku [17]
<span>It's another energy balance equation, though: energy to start with is the same as energy that you end with. Suppose that we start a distance r0 from the Earth and end a distance r1 from the Moon, then the energy balance gives: 1 v02 - G M / r0 - G m / (D - r0) = 1 v12 - G M / (D - r1) - G m / r1 ...where m is the moon's mass. One simple limit takes D ? ? and 1 v02 ? G M / r0 (the escape velocity equation), to yield: 1 v12 ? G M / r1 v1 ? ?( 2 G M / r1 ) = 2377 m/s.</span>
