Around 8 minutes, 150Gm/300Mm/s=500 seconds or 8.333 seconds.
About 35% of the light that hits the Earth is reflected away immediately, back into space. The remainder of the light hits the Earth. Some of it is absorbed or scattered in the atmosphere, and much of it reaches the surface as light. Sunlight that is absorbed by the surface heats the Earth.
Lots!
The Earth looks bright - thus much of the light reaching Earth is reflected back into space.
half a billionth
its about just 1%
it is 70% so that is the answer of how much light on the earth surface
Jupiter receives very little sunlight. About 5 Astronomical Unit (AU) or 1/25th the amount of sunlight that the Earth receives, reaches the surface of Jupiter.
A planets visibility from Earth depends on its distance, distance from the sun and size. Smaller and/or further planets will be much dimmer. Venus can be the brightest, but it is much smaller than Uranus or Neptune for example. It is more visible due to it being much closer, and closer to the sun.
Saturn does not generate its own star light, but instead reflects the light of our sun. At 9 AU, 1/9^2 as much solar energy reaches Saturn as Earth. That is a little more than 1%.
Dim fog. Saturn is a gas giant so there is no hard "surface", it is far from the Sun so there is much less light reaching it than reaches Earth.
it has light for 12 hours
Mars is always further away from the sun than the earth is. Therefore, the light that reaches the surface on mars is much weaker than on earth, so solar panels are not quite as effective.
