How are the four inner planets similar?

THEY ARE SMALL AND HAVE ROCKY SURFACESThey have a rocky surface, also known as terrestrial planets.They are rocky in their composition.They are roughly similar in size and density, and are all closer to the sun than the gas planets.


what Scientists refer to half of the planets as inner planets because they are relatively close to the Sun. They refer to the other half as outer planets. Using the data in the table, classify the planets into one of the two groups.?

One-half of eight is four. So, there are four inner planets and four outer planets. According to the distances in the table, Mercury, Venus, Earth, and Mars are inner planets. Jupiter, Saturn, Uranus, and Neptune are outer planets.


Why are mercuryvenusearthand Mars inner planets?

the four inner planets (mercury, venus, earth and mars) are called the inner planets because they are quite close to the sun. where as the four outer planets ( jupiter, saturn, uranus and neptue) are a lot further away from the sun.


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.


Do the outer planets circle the inner planets?

All planets circle the CEntral Star. So in a way outer planets almost circle inner planets but the Star is at one focus of the planets' orbits so it is more proper to say that planets orbit stars.


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.


How are the four inner planets similar to one another?

If you are talking about Mercury,Venus,Earth, and Mars, they are all terresrial. And they are all close(r) to the sun. Also they all have solid surfaces, compared to the outer planets, which most of them have gas surfaces


What are the four planets that have orbits from most to least?

All the planets have orbits so four cannot be picked out.


What is different between inner and outer planets?

1-Outer Planets are much colder then inner planets. 2-They are all Gas Giants (they are incredibly huge). 3-ALL outer planets have rings (Pluto is a dwarf planet.And is alot farther away then Neptune) 4-There gravity is ALOT stronger then the inner planets. 5-Outer planets have shorter days then inner planets (i don't know why though).


What is the difference between inner and outer planets?

The four inner planets are smaller, denser and warmer than the four outer gas planets. The four gas planets don't have clear surfaces like the four inner rocky planets. Because they are further away, the out gas planets orbit the sun at slower speeds and at slower rates - taking much longer in general. The four outer planets have a very different composition to the inner planets.The inner planets and the outer plants are divided by the asteroid belt.The inner planets are small and comprised mainly of rock and metals.The outer planets are large and are comprised mainly of gases and ices.However, it was believed that other planets close to another star couldn't be gas giants, but the discovery of a "hot Jupiter" extrasolar planet whose mass is close to or exceeds that of Jupiter orbits within 0.05 AU of it's parent stars, about one eighth of the distance that Mercury orbits the Sun.the inner planets are rocky and within the aesteroid belt. the outer planets are made from gas and ice and are outside the belt.The inner planets are between the Sun and the Asteroid Belt, while the outer planets are farther from the Sun than the Belt.The "inner planets" are the four rocky or "terrestrial" (Earth-like) planets closer to the Sun. The outer planets are the four larger "gas giants".Inner planets : Mercury, Venus, Earth, MarsOuter planets : Jupiter, Saturn, Uranus, Neptune


What is the general composition of all inner planets?

the mass and the weight of all gas planets. And when you form them to be all as one then you can make sure that you see the solar system as one and you want to be perfect with the way that you do it. So when you take all the planets together and you take away the ones that are not gas planets then you add the mass and the weight of the planets and then you get the general composition of all of the basic inner planets.


What is the inner planets?

Can't answer because there are no choices offered.
