Webb28 maj 2024 · However, because the angle θ is so small, to a good approximation θ = tan (θ). So θ = -v/c If we take A as equal to 0 degrees, this means that the star lies in the same direction as the Earth is moving. So, sin (A) = 0, which means θ = 0 and the star is unchanged in position. http://seaver-faculty.pepperdine.edu/dgreen/Nasc109/HandoutsSolutions/SmallAngleFormula.pdf
