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 volatile substances (which are
Our Solar System
Our solar system has four giant planets: Neptune, Uranus, Saturn, and Jupiter. Giant planets are much larger than Earth—they are unimaginably huge, stunningly beautiful, and sometimes a little weird. They are made mostly of gases instead of solid materials, and a host of Moons orbits each one. Neptune and Uranus likely have regions of ices

Types of Giant Planets Gas Giants . The Solar System''s two gas giant planets, Jupiter and Saturn, are composed primarily of hydrogen and helium. In addition to
The Gas Giant Planets
Beyond the asteroid belt lies the outer Solar System. This region is dominated by four giant planets, which range in size from about four to ten times the diameter of Earth. Jupiter, Saturn, Uranus, and Neptune have massive gaseous atmospheres, so are often called gas giant planets. Because Jupiter dominates these planets, they are also referred to as Jovian planets.

They represent the least-explored category of planet in our solar system. Scientists using Webb plan to study the circulation patterns, chemistry and weather of Uranus and Neptune in a way only Webb can.
EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM
To this end, it is worth noting that although the primordial planetesimal disk of the solar system likely comprised tens of Earth masses (Tsiganis et al. 2005; Levison et al. 2008, 2011; Batygin et al. 2011), the vast majority of this material was ejected from the system by close encounters with the giant planets during, and immediately

The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

Planets – classification, primary planets, dwarf planets, comparison
Mercury — the closest to the sun and the second smallest planet in our solar system, Mercury has a rotation of only 88 days around the sun. Because of its close proximity to the celestial giant, the surface of the planet reaches temperatures as high as 840°F during the day and hundreds of degrees below the freezing point at night.
Gas Giants: Facts about the 4 Outer (Jovian) Planets
Gas Giants. A gas giant, also known as a jovian planet after the planet Jupiter, gaseous giant, or giant planet, is a large planet which has at least ten times the mass of Earth, located in the outer solar system.
Gas Giant Facts (The Outer Planets)
Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores). The four gas giants in our solar system are Jupiter, Saturn, Uranus, and Neptune.

What Are The Ice Giants?
Characteristics of Ice Giants . Ice giants are one of three types of planets in the Solar System, along with gas giants and terrestrial planets. About 90% of the mass of gas giants is composed of helium and hydrogen, while the remaining 10% consists of a small rocky core. Ice giants are composed of sulfur, nitrogen, carbon, and oxygen.

In the outer solar system, turbulent storms dot the atmospheres of the giant planets — Jupiter, Saturn, Uranus, and Neptune — allowing Hubble to become an expert storm tracker. For instance, Hubble has observed the downsizing of Jupiter''s most famous feature, the spinning, cyclone-like storm known as the Great Red Spot.
7.2 Composition and Structure of Planets
Chemically, each giant planet is dominated by hydrogen and its many compounds. Nearly all the oxygen present is combined chemically with hydrogen to form water (H 2 O). Chemists call such a hydrogen-dominated composition reduced. Throughout the outer solar system, we find abundant water (mostly in the form of ice) and reducing chemistry.

6 FAQs about [Giant planets in the solar system]
How many giant planets are in the Solar System?
The Solar System contains four giant planets: Jupiter, Saturn, Neptune, and Uranus. Compared to Earth, these massive celestial bodies are located significantly further away from the Sun. The Solar System's two gas giant planets, Jupiter and Saturn, are composed primarily of hydrogen and helium.
What is the largest planet in the Solar System?
Jupiter is the largest planet in our solar system by size, mass, and volume. By size, Jupiter is gigantic, having a diameter of 142,800 kilometers or about 11 Earths across. In terms of volume, you could fit every other planet inside Jupiter, and there would still be space left over. Jupiter is more than 300 times the mass of the Earth.
Is Jupiter a giant planet?
Unlike terrestrial planets such as Earth, Jovian planets are all giant planets and they're primarily made up of hydrogen and helium. One of the four Jovian planets, Jupiter is the largest planet in the solar system. As a matter of fact, the giant planet is two-and-a-half times as massive as all the other planets in the solar system combined.
What planets are in the Solar System?
Solar System bodies Comets Damocloids Meteoroids Minor planets names and meanings moons Planetesimal Planetary orbit-crossing minor planets Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Trojans Venus Earth Mars Jupiter Trojan camp Greek camp Saturn Moons Uranus Neptune Near-Earth objects Asteroid belt Asteroids Ceres Vesta Pallas Hygiea
Are Jupiter and Saturn the largest planets in the Solar System?
The outer solar system contained vast amounts of hydrogen and helium, allowing planets like Jupiter and Saturn to become the largest planets in the solar system. Interestingly, Jupiter and Saturn are probably the two most similar planets in the solar system. Both are composed chiefly of hydrogen and helium and are covered in large bands of gas.
Why are there two giant planets in our Solar System?
Models suggest this may be due to there being two giant planets in our Solar System, as the presence of a third or more giant planets tends to induce larger eccentricities. The axial tiltof Jupiter is 3.13°, which is relatively small, so its seasons are insignificant compared to those of Earth and Mars.
