Terrestrial Planets: solid surfaces, slower rotation, less dense metal cores Jovian Planets: Non-solid surfaces, faster rotation, much denser hydrogen + metal cores
Coming from the Latin word "terra" meaning "land", the terrestrial planets are Mercury, Venus, Earth, and Mars.
All the terrestrial planets are closer to the sun then the Jovial planets, and the terrestrial planets are also smaller. In addition, terrestrial planets rotate slower, lack rings, and have less moons. The main atmosphere of terrestrial planets is a gaseous mix of carbon dioxide and nitrogen gases, and all terrestrial planets have rocky surfaces. The cores of the terrestrial planets are mainly dense iron with silicate, and although jovian planets have denser cores, terrestrial planets overall ar more dense.
Jovian planets: The jovian planets, so named because of their resemblance to Jupiter, are composed of the rest of the planets in the solar system (except Pluto), so Jupiter, Saturn, Neptune, and Uranus.
