A parsec is equal to the distance … Web10 dec. 2024 · Remember, a radian is 57.3 degrees, which is (57.3 x 60 x 60) arc seconds, or 206,265 arc seconds, so 1 arc second = 1/206,265 of a radian. Then 1 parsec = 1 AU / (1/206,265), or 206,265 AU. In the distance from the nebula, 6,500 many years, the size could be 200 arcseconds = 6,500/1000 x 1 light year = 6. 5 many years.
