There are four outer planets : Jupiter, Saturn, Uranus and Neptune.

All are gaseous and more massive than the Earth.

Pluto was once designated as a planet, but was reclassified as a "dwarf planet". The four "inner planets" are Mercury, Venus, Earth and Mars.

How do the inner planets differ from the outer planets?

The inner planets are solid and aircrafts can land on them. Their temperatures are higher because the are closer to the sun. The outer planets have colder temperatures and less sunlight because they are farther away from the sun. The outer planets are also called the Gas Giants because they are made out of gas. Inner Planets: Mercury, Venus, Earth, Mars Outer Planets: Jupiter, Saturn, Uranus, Neptune Dwarf Planets: Pluto, Ceres, eris, Makemake, Haumea


Why do they call some planets Inner and Outer planets?

The inner and outer planets are broken up by the asteroid belt between Mars and Jupiter. Mercury, Venus, Earth, and Mars are "inner planets" because they are on the side of the asteroid belt closest to the sun. All other planets are considered "outer planets".


What are 3 differences between the outer and inner planets?

The inner planets are small, the outer planets are huge in comparison.The inner planets have rocky surfaces, the outer planets are gas giants.All of the outer planets have rings. None of the inner planets does.All of the outer planets have several moons, some of them quite large.


What is the difference between the first four planets and the last four planets?

The four inner planets are smaller than the four outer planets. The inner planets are made up mostly of iron and various types of rock. The outer planets are mostly hydrogen, helium, and ice. The inner planets each completely rotate in less than an earth day. The inner planets all rotate faster than the outer planets.


What are the four planets closets to the sun?

the first 4 planets near the sun are called the inner planets or the terrestrial planets as they are made of rocks. the outer planets (jupiter, uranus, neptune and pluto) are called the outer planets or the jovian planets.. theis is because they are made up of liquids/gases.... hope it helped! thanx!! :)
