Inner Planets are also called Terrestrial Planets because they are solid, dense and are made up of rocks

​

​The Inner

Planets

​

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.

​

OUTER PLANETS​

ØKnown as the “king of the planets”

ØIts most prominent feature is the “Great Red Spot.”

ØHas 16 moons, 4 of which are known as the “Galilean satellites.”.

​

JUPITER​

ØThe second largest gas planet.

ØHas more than 31 moons and the largest is Titan

​

SATURN​

ØUranus rotates in the opposite direction as most other planets. And unlike any other planet, Uranus rotates on its side.

ØHas 13 rings and 27 known satellites/moons.

​

URANUS​

ØThe planet farthest from the sun.

ØKnown as the “twin planet” of Uranus

It has 8 known moons.

​

NEPTUNE​

The four planets farthest from the sun are known as the outer planets. Jupiter, Saturn, Uranus, and Neptune.

Inner Planets are also called Jovian Planets because they are made up of gas.
