Summer Variation Lab Report
The planet that I would expect to exhibit the greatest variation in apparent brightness, as seen from Earth, would be Mars. There are a few reasons for this, but for the most part it is due to its eccentric orbit and the variance of distance between the planet and the Earth. No other planet varies as much in brightness as Mars due to this variance in distance. At its brightest point, Mars is almost impossible to see because it is so close to the Sun.
