The outer planets are gas giants Jupiter and Saturn and ice giants Uranus and Neptune. Beyond Neptune, a newer class of smaller worlds called dwarf planets reign, including longtime favorite Pluto. Thousands more planets have been discovered beyond our solar system.
What are the 4 outer planets in order?
From left to right, the outer planets are Jupiter, Saturn, Uranus, and Neptune. The gas giants are made up primarily of hydrogen and helium, the same elements that make up most of the Sun.
What are the 8 outer planets?
The outer planets are Jupiter, Saturn, Uranus, and Neptune. Jupiter, Saturn, Uranus, and Neptune are large balls of gases with rings around them. All eight planets travel around the Sun in a different orbit.

What are 4 characteristics of the outer planets?
The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings.
What are the 4 gas planets?
The planet Jupiter, Saturn, Uranus and Neptune are sometimes called the Gas Giants because so much of the mass of these planets consists of a gaseous atmosphere.
Is Uranus an outer or inner planet?
A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets reside in the outer part of the solar system past the orbits of Mars and the asteroid belt.
Is Venus an outer planet?
The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.
What planet is Uranus?
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
Is Pluto an inner or an outer planet?
The planets inside the asteroid belt are termed the Inner Planets (or the Terrestrial Planets): Mercury, Venus, Earth, and Mars. The planets outside the asteroid belt are termed the Outer Planets: Jupiter, Saturn, Uranus, Neptune, and Pluto.
Why is Pluto not a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Do all the outer planets have rings?
For a very long time, Saturn was thought to be the only planet in our solar system with rings. … Since then, astronomers – who study the universe and everything in it, like planets – have used bigger and better telescopes to find rings around all of the outer gas giant planets: Jupiter, Saturn, Neptune and Uranus.
What is Jupiter Saturn Uranus and Neptune?
The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune. … It is now a dwarf planet. The outer planets are also called the gas giants because of their composition.
What do the outer planets have in common?
What are 4 things the outer planets have in common? The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
How are the outer planets different?
Outer planets differ from inner planets in composition, size, distance, and mass. … Unlike inner planets, outer planets are larger and spaced farther apart. Also, inner and outer planets are separated by the asteroid belt; inner planets closest to the Sun, outer planets farthest from the Sun.
What are Saturn’s rings made of?
Rings. Saturn’s rings are thought to be pieces of comets, asteroids, or shattered moons that broke up before they reached the planet, torn apart by Saturn’s powerful gravity. They are made of billions of small chunks of ice and rock coated with other materials such as dust.
