This is purely an educated guess! The outer planets are a lot bigger than the ones closer to the sun in orbit. This means that the gravitational pull of these planets is a lot greater also. This much I know for sure. I would think that since they have more gravitational pull, they probably attract more asteroids and other space debris to themselves that end up in orbit around those planets. because they have lot of gravity and other physical makeup such as ice,gas and so furth,that will eventual result when gravity pull and interract with those properities it form craters moons. pure education guess. it is the collision of hydrogen and helium added with gravity it causes them to have more moons

∙ 14y agoFarther from the Sun, the solar system contains much less heat than the area nearer the Sun where the Earth is. Because of this low temperature, objects that were condensing captured hydrogen-rich materials like methane, ammonia, and especially water. There was much more of these materials in the solar system than the iron rich material that the terrestrial planets are made of. This allowed the cold planets to become much larger than the planets closer to the Sun.

∙ 13y agoBecause they are too close to the sun! The outer planets (gas giants) have rings because there is was more debris left over from when they formed so it turned into moons (all of the outer planets have loads!) and rings. However mars might have a set of rings one day because its moon Phobos is gradually spiraling closer to the planet this means that it will eventually either crash into the surface of mars- sending debris up into space to create moons and/or rings or gravity will pull it apart and it will form rings!
Hope this helps!xxx :-)

∙ 7y agoThe rings of the outer planets are a result of past moons breaking apart from tidal interactions. This happens only in systems where the mass of the planet is very large, and there are many moons.

What describe the outer planets?
Large, gaseous and cold
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 best describes the outer planets?
Large, gaseous and cold
Why are some planets referred to as outer planets?
The planets in the solar system can be sorted to two types: inner planets that are the four closer planets to the Sun, which are rocky and small. And outer planets which are the four other planets which are gaseous and very large.
Why does it take the outer planets so long to orbit the Sun?
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
What dowe call the four large outer planets?
The 4 outer planets are Jupiter , Saturn , Uranus and Neptune
Are the inner planets large planets made up of mostly gas?
No, those are the outer planets.
Why would the average densities of the four large outer planets be so low when compared with the average densities of the inner planets?
Because the outer planets are composed of mainly gas or ice, whereas the inner planets are composed of rock which has a higher density.
What do the the outer planets have in common?
They are all gas planets. They are all quite large and made from gas, so there is no real surface like that of earths.
What describe the outer planets?
Large, gaseous and cold
What are large planets called gas or terrestrial?
large planets are called the outer planets or the JOVIAN PLANETS which are made up of gases and viscous liquids... terrestrial planets are the inner planets! inner planets- MERCURY VENUS EARTH MARS outer planets- JUPITER SATURN URANUS NEPTUNE

Are the Jovian planets outer planets or inner?
There are four inner planets (Mercury, Venus, Earth and Mars) and four outer planets (Jupiter, Saturn, Uranus and Neptune). So there are an equal number of inner and outer planets.

Why are the inner planets smaller and made of rock while the outer planets are large and made of gas?

What is the size of the outer planets?
The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.
