 One very interesting fact is that the earth is smaller than the cores of these planets. Each of the giant planets harbor a solid sphere the size of the earth at their center.

 ==== - The moons ====
 Only Earth and Mars among the terrestrial planets have moons, or natural satellites. Our moon is the 'moon', but the natural satellites of other planets are sometimes also called 'a moon'. Almost 300 moons have been discovered. Any object orbiting a planet is a moon no matter how small. But only 19 of the almost 300 moons are big enough to be completely round in shape because of their self-gravity.
