Julee July 20, 2016, 09:40:47 AM #1 Answer Mars and Venus, in addition to being conveniently nearby, are very similar to Earth is size and the existence of an atmosphere (denser on Venus, much less dense on Mars). The similarities mean that these planets can be used to test the same physics and physical models used on Earth (with changes appropriate to conditions on the respective planet) to see whether they can make predictions for all three planets.
