Explanations
Draft
Iapetus is one of the most remarkable moons in our solar system: its two hemispheres have dramatically different brightness, which makes it truly unique. A striking feature is the equatorial ridge, which rises up to 20 km high – one of the most spectacular mountain ranges in the outer solar system. With a diameter of 1469 km, Iapetus takes almost 80 days to orbit Saturn and is located over 3.5 million kilometers away from it.
