Your idea that the sun's apparent and actual positions are off by 2.1 degrees.

When you see the light from the Sun, is the Sun exactly where you see the light coming from it or is the Suns position off by the amount of time it took for the light to get to the Earth from the Sun (8.3 minutes) and the angular rotation of the earth, 2.1 degrees (your frame of reference) that occurs in 8.3 minutes?

Now, can you back that claim up?

Wikipedia should have something on it, right?

Diurnal aberration perhaps?

Said LeGrande: When you see the light from the Sun, is the Sun exactly where you see the light coming from it or is the Suns position off by the amount of time it took for the light to get to the Earth from the Sun (8.3 minutes) and the angular rotation of the earth, 2.1 degrees (your frame of reference) that occurs in 8.3 minutes?

But wouldn't that also mean that when Pluto was at the part of its orbit which brought it the most distance from the earth, at which point the time of light travel is 6.8 hours in which time the earth rotates 102 degrees -- does that mean then that if I look up through my telescope and see pluto overhead it actually won't even be in the night sky at that time, but rather 102 degrees away from where I see it?

And what about a heavenly body that was 12 light hours away - would it appear to be exactly in the opposite side of the sky of where it really was? Would it's gravity be 180 degrees out of phase with its apparent position?
