pThe Sun's angular diameteris measured to be 1920 The distance Dofthe Sun from the Earth is 1.496 x 10mWhat is the diameter of the Sun? |
|
Answer» the Angular diameter is the angle subtended by the diameter of the Sun planet at the eyes of a viewer.δ = angular diameter in radiansd = actual diameter of Sun planet D = distance between the surface of Earth and Sun. = 1.496 * 10^11 meterstan δ/2 = (d/2) / D δ in radians = δ in arc seconds / 3600 * π/180 = 1920/3600* π/180 radiansd = 2 D tan δ/2 = 1.39*10^9 meters= 1.390 &10^6 km Earth's diameter = 12,742 km Sun's diameter is around 109 times Earth's. so it is 1388872 km= 1.388 * 10^6 km. |
