Our solar system has two classes of planets: terrestrial planetsand jovian planets.

Terrestrial planets: Terrestrial means“earth-like” planets. “Terra” is another name for Earth. Mercury, Venus, Earth & Mars. Terrestrial planets are small, “rocky”, high density & orbit close to the sun. Someday, humanity may colonize the other terrestrial planets for the benefit of Humankind!

Earth moves in two ways simultaneously: Revolves around the Sun 10 per day. One complete revolution is 364 ¼ days Rotates on its axis 150 per hour

Jovian planets The “Jupiter-like” planets. Jove was another name for Jupiter. Jupiter, Saturn, Uranus, Neptune. They are very large, low density, made completely of gases such as Hydrogen, helium, methane & ammonia. They used to all be called: “the gas giants” Jupiter and Saturn are called the “gas giants” Uranus and Neptune are the “ice giants”

Saturn: density is less than water. Would float in water!
