If the Sun's distance were three times its current distance, the "surface brightness" (apparent brightness per unit angular area) would be equal to its current surface brightness. 1/3 its current surface brightness. 1/9 its current surface brightness. 9 times its current surface brightness. 3 times its current surface brightness.
