INNER VS OUTER
EIGHT PLANETS, TWO STYLES
Our solar system has eight major planets in two groups. The inner four, Mercury, Venus, Earth, and Mars, are rocky terrestrial planets. They have dense metal cores and solid crusts made of rock. The outer four, Jupiter, Saturn, Uranus, and Neptune, are giant planets with thick atmospheres and no solid surface to walk on. A spacecraft diving into Jupiter would never hit ground, only denser and denser gas.
🪨 ROCKY
Terrestrial planets have solid surfaces and are relatively small and dense compared with the giants.
