Originally posted by aging blitzerI got a lot more than that.
Assuming it approaches within 4 solar radii of the surface of the sun
then it is on a sphere of radius 5 solar radii
or 3,475,000 km
Earth's distance from the sun ranges between 146-152,000,000 km
Assuming 149,000,000 km
and calculating the surface areas of the spheres (or just comparing 3.475 squared and 149 squared) you find the 1 AU sphere ...[text shortened]... f 1838 times bigger than that of the 5 solar radii.
So about 2,500,000 watts per metre squared
