Question

Given the following characteristics for Mars and Jupiter:

          Sun diameter                          = 1.4 x 10⁶ km

           Mars diameter                        =6860 km

           Jupiter Diameter                    =143,600 km

           Sun-Mars distance                 =228 x 10⁶ km

           Sun-Jupiter distance              =778 x 10⁶ km

           Mars albedo                           =16%

           Jupiter albedo                        =73%

           Solar output                           =6.2 x 10⁷ Wm^-2

Q : Solid angle subtended by the sun

Answer 1

First calculating angular diameter then calculating solid angle.
