... 5. The Andromeda galaxy has an angular diameter of 5 degrees at a distance of 2.2x106 ly. We can find its true size by using the angular diameter formula L = 2DA/360, where D = distance, A = angle subtended, and L = linear diameter. Thus, L = 2 x 2.2x106 ly x 5 degrees / 360 degrees = 1.92x105 ly ...
