Question

Part G The point of origin of a typical asteroid might lie at a radius of about 3 AU (astronomical units; 1 AU = 1.5 × 10¹¹ m) from the sun, the approximate location of the asteroid belt. Calculate the effective target cross section S of the earth as seen by the asteroid. Assume the asteroid's orbit is circular. Give your answer as a multiple of the area of the disk of the earth, ?R².

Step 1

The effective target cross section \(S\) of the Earth as seen by an asteroid is essentially the area within which the asteroid must enter in order to collide with the Earth. This area is larger than the actual cross-sectional area of the Earth due to the Earth's Show more…

The point of origin of a typical asteroid might lie at a radius of about 3 AU (astronomical units, 1 AU = 1.5 x 10^11 m) from the sun, the approximate location of the asteroid belt. Calculate the effective target cross section S of the earth as seen by the asteroid. Assume the asteroid's orbit is circular. Give your answer as a multiple of the area of the disk of the earth, ̀πR².
