Observation of the sun?

Question

A the sun has a brightness when viewd from Earth. how much dimmer would the sun appear if you were standing on Jupitor (which is 5 times further from the sun than Earth)? How about if you were looking at the sun from Pluto (which 40 times further from the sun than Earth)?

Help, im stuck I dont get this pleae helps

Answer 1

Light intensity diminishes by the square of the distance, so if Jupiter is 5 times farther, it would appear 1/25th as bright as on earth.

Answer 2

Brightness or intensity obeys the inverse square law. The Sun would appear 1/25 as bright from Jupiter as it does from Earth, and 1/1600 as bright from Pluto. Another way of looking at this is that, since the surface area of a sphere is 4πr^2, the area of the sphere surrounding the Sun at Jupiter's distance is 25 times the area of the sphere around the Sun at Earth's distance, and the area at Pluto's distance is 1,600 times that at Earth's distance.

Answer 3

If it was 40 times farther it wouls be 40 times smaller and 40 times dimmer for the most part. Not too much out there to make much else different (clouds of nebula ect).

Answer 4

The intensity goes as 1 divided by the square of the distance. Do the math.
