They are all composed of gasses.
The four inner, terrestrial or rocky planets all have similar densities, much higher than the four outer gas giant planets (though the outer planets are much larger and more massive).
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.
The inner planets are smaller than the outer planets.
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
The four outer planets are all of the type astronomers call "gas giants", and have no hard, rocky surface per se. The inner planets are all solid rocky "terrestrial" planets. Also, the four outer planets are larger in size and lesser in density than the inner planets.
The four inner, terrestrial or rocky planets all have similar densities, much higher than the four outer gas giant planets (though the outer planets are much larger and more massive).
they orbit the sun and are the first four outer planets
They are similar in that both the inner and outer planets all orbit the sun.
The outer planets are the planets that are made of gas. Each of the outer planets are mad of gas and can not hold life.
The four inner planets are all made of rock or are rock based but the four outer planets are all made of gas or gas based.
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.
The inner planets are smaller than the outer planets.
the first four outer planets are Jupiter, Saturn, Uranus, and Neptune.
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.
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
All the outer planets probably have solid cores. However, they do not havewhat we call a solid surface.Incidentally, there are only four outer planets altogether.There are only 4 "outer planets". They do not have a solid surface.
Each of the four outer gas planets has a ring system. These four outer planets are Jupiter, Saturn, Uranus and Neptune.
