A refracting telescope with a lens whose diameter is 25.0 cm is used to view a binary star system that emits light in the visible region.
Part A]
What is the minimum angular separation of the two stars for them to be barely resolved?
\theta_{\rm min} =1.95×10^-6 \rm rad
Part B]
If the binary star is a distance of 9.00×10^20 km from the Earth, what is the distance between the two stars? (Assume that a line joining the stars is perpendicular to our line of sight.)
??
I solved Part A. But I can't seem to get Part B. I used the S = Theta distance equation but I can not seem to get the answer. I got 1.76 *10^12 but it said it was wrong.
