In general, the further planets are from the Sun, the cooler they are. What other factor can have a significant influence on a planet's surface temperature?
A) its atmosphere (whether it has one and how thick it is)
B) the number of large moons that are close to the planet
C) how fast the planet is spinning (the length of its day)
D) whether its core has a lot of iron in it
E) none of the above (only distance from the Sun affects a planet's temperature)
