The four giant planets of the Solar System: (top) Jupiter and Saturn (gas giants) (bottom) Uranus and Neptune (ice giants) Shown in order from the Sun and in true color. Sizes are not to scale. A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger ...
A gas giant is a giant planet composed mainly of hydrogen and helium. [1] Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet". However, in the 1990s, it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier ...
List of largest exoplanets. Jupiter as seen by Voyager 1 in 1979. It is the largest planet having its surface resolved [1][2] [3] and it is the largest planet in the Solar System. [4] Below is a list of the largest exoplanets so far discovered, in terms of physical size, ordered by radius.
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun.
An ice giant is a giant planet composed mainly of elements heavier than hydrogen and helium, such as oxygen, carbon, nitrogen, and sulfur. There are two ice giants in the Solar System: Uranus and Neptune. In astrophysics and planetary science the term "ice" refers to volatile chemical compounds with freezing points above about 100 K, such as ...
The Kuiper belt (/ ˈkaɪpər / KY-pər) [ 1 ] is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. [ 2 ] It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. [ 3 ][ 4 ] Like the asteroid belt ...
The inner Solar System is the region comprising the terrestrial planets and the asteroids. [ 89 ] Composed mainly of silicates and metals, [ 90 ] the objects of the inner Solar System are relatively close to the Sun; the radius of this entire region is less than the distance between the orbits of Jupiter and Saturn.
Jupiter is the biggest planet in our solar system, according to NASA. The planet is what’s known as a gas giant, which means it doesn’t have a solid surface — though it may have a solid core ...
