Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It has a whopping 145 moons. It's the farthest planet from Earth that's visible to the unaided eye, but the planet's most outstanding features — its rings — are better viewed through a telescope. It is a gas giant with an average radius of about nine-and-a-half times that of Earth.

Mars is the fourth planet from the sun and has a distinct rusty red appearance and two unusual moons. The Red Planet is a cold, desert world within our solar system. It has a very thin atmosphere, but the dusty, lifeless planet is far from dull. The surface of Mars is orange-red because it is covered in iron oxide dust, giving it the nickname "the Red Planet".
