Estimate the surface temperature of Mercury (the planet). Mercury is distant 0.38 ORE from the Sun, where the Earth-Sun distance, ORE is 1.49.108m. The radii of the Sun, Earth and Mercury are 696.103, 6.38.103 and 2.42.103 km respectively.
Heat (IR Radiation) follows inverse square Law
The Attempt at a Solution
See I am confused with why the Sun Earth and Mercury's radius are on here. I know that Infra Red radiation follows the inverse square law, so I would ave thought you would have used this to find the temperature on Mars, however, the radius are given, so I am slightly confused...is there more to this question???
Thanks in Advance,
