The four outer planets - Jupiter, Saturn, Uranus, and Neptune - are known as the external or gas giant planets. They are the largest planets in the solar system and are divided into two groups: gas giants like Jupiter and Saturn that are primarily composed of gaseous materials, and ice giants like Uranus and Neptune that have higher proportions of ice and rock in their compositions compared to the gas giants.

1. ●The Planets located outside the Orbit of mars are
known as external planets, while the ones that
gravitate inside the orbit of mars are termed
interior planets (including mars).

2. External Planets
● The external planets, are the four planets
farther to the sun. (Jupiter, Saturn, Uranus, and
Neptune)
● They are the biggest planets of the solar sistem,
and they're divided in 2 groups.

3. Gas Giants
● That are composed of gaseous materials
(Jupiter and Saturn)
The most massive planet in our solar system,
with dozens of moons and an enormous
magnetic field
Adorned with thousands of beautiful ringlets,
Saturn is unique among the planets. All four
gas giant planets have rings, made of chunks
of ice and rock, but none are as spectacular
or as complicated as Saturn's.

4. Ice Giants
● They are also composed of gaseous materials
but they have a higher proportion of rock and
ice.
Dark, cold and whipped by supersonic winds,
Neptune is the last of the hydrogen and
helium gas giants in our solar system.
More than 30 times as far from the sun as
Earth, the planet takes almost 165 Earth
years to orbit our sun.
Uranus is the only giant planet whose equator is nearly
at right angles to its orbit. A collision with an Earth-sized
object may explain the unique tilt. Nearly a twin in size
to Neptune, Uranus has more methane in its mainly
hydrogen and helium atmosphere than Jupiter or Saturn.
Methane gives Uranus its blue tint.
