The similarities between earth and other inner planets

In our Solar System, which consists of eight planets total, there are four inner and four outer planets, with the asteroid belt between them.

The similarities between earth and other inner planets

They are also sometimes known as the Gas Giants as they are all huge in comparison to the Inner Planets and made up mostly of gas so don't have solid surfaces. The first of the Outer Planets is Jupiter. It is also the largest of the Outer Planets and is so big that Earth could fit into it 1, times!

Jupiter is a massive , miles away from Marsthe last of the Inner Planets. Neptunethe smallest and most distant, is still big enough to contain 60 Earths! Like the Inner Planetsthe Outer Planets share similarities but each also has its own unique characteristics. As well as all being huge and being made up mostly of gases, all four have rings spinning around them, with Saturn having the most famous rings.

All four planets also have large numbers of moons orbiting them. The picture below shows the orbits of the Outer Planets, also including Plutoa dwarf planet which crosses the orbit of Neptune and was also once classed as an Outer Planet.

It also shows how close the Inner Planets are to each other, appearing as a ball in the middle of the picture, although even those are millions of kilometres away from each other. It also shows the orbits of three comets: Despite their similarities, each planet has its own characteristics, although none of them, apart from Earthare known to be able to support life.

Below is a short description of each planet.

For a more detailed look at the planet, select on the planet's name. Jupiter Jupiter is the biggest planet in the Solar System.

Terrestrial Planets: Definition & Facts About the Inner Planets

A day on the planet only takes 9 hours and 55 minutes, meaning that the planet spins very fast, although a year on Jupiter the length of time it takes for the planet to orbit the Sun takes This is because the planet is so far away from the Sun.

The planet is made up mainly of hydrogen and helium, and, as far as we know, does not have a solid core although may have a metallic liquid hydrogen core. Jupiter also has a magnetic field which would make the planet appear as big as the Sun if it was visible.

Its main feature is a Great Red Spotwhich is a storm that has been going on for years. The planet has 79 known moons, including Ganymedethe largest moon in the Solar System which is larger than the planet Mercury and dwarf planet Pluto! Saturn Like JupiterSaturn is also made up mainly of hydrogen and helium.

It is so full of gas that its density the amount of matter in an area is so low that, if there was a sea of water big enough, it would float on it! Saturn takes 10 hours and 39 minutes to turn on its axis, so, everytime a day has passed on Earthover two days have passed on Saturn.

But the planet, being so far away from the Suntakes 29 and a half Earth years to completely orbit the Sun. Saturn's most famous feature are its great ringswhich appeared like ears when Galileo Galilei observed Saturn in the Seventeenth Century.

These are rings of small dust, rock and ice particles, probably what remains of a shattered moon which once orbited Saturn. Saturn has at least 62 moons orbiting it.Which planet is most similar to Earth?

(Intermediate) But Mars is the planet that is most similar to Earth in other ways. A Martian day is just over 24 hours, and its rotation axis is tilted by about the same amount as Earth's. Have the inner planets cleared their neighborhood?

(Intermediate) What caused the Big Bang and created the. inner planets: Mercury, Venus, Earth and Mars. outer planets: Jupiter, Saturn, Uranus, Neptune.

The asteroid belt between Mars and Jupiter forms the boundary between the .

The similarities between earth and other inner planets

The 4 inner planets are small, rocky planets (Mercury, Venus, Earth, Mars). Then there is an asteroid belt of leftover parts and debris, then the 4 outer gas giants (Jupiter, Saturn, Uranus, Neptune).

The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. Separated by the asteroid belt between Mars and Jupiter, they’re on the other side of it than the inner planets.

The outer planets include Jupiter, Saturn, Uranus and Neptune. They should be distinguished from superior planets, which are those that are further away from the . It is also the largest of the Outer Planets and is so big that Earth could fit into it 1, times!

Jupiter is a massive ,, miles away from Mars, the last of the Inner Planets. Neptune, the smallest and most distant, is still big enough to contain 60 Earths!
