"Actually, you measure the incoming angle from the starlight at two opposite positions of the earths orbit and using the incoming angle and the earth's speed the speed of light was calculated. Done about 200 years ago but they got within about 1%."

Not really close enough I'm afraid, and it ignored the effect of gravity on the distance the light traveled. While it did result in a decent approximation, it was a flawed measurement.

I am sure you could get closer today with modern instruments.
