No that's what the four outer planets are called.
The inner planets are all terrestrial - they are "rocky". The outer planets are gas giants.
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
They are alike because they are both called planets, both terrestrial planets and gas giants are spheres, all have a somewhat dense core and lastly all orbit around the sun.
They are all called gas giants, primarily because they are predominantly gas and massive compared to the inner planets. There are several theories why this should be so but there is no definitive answer.
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.
All the inner planets in our solar system are all terrestrial planets. They are all small rocky planets with a relatively small atmospheres when compared to the gas giants like Jupiter and Saturn or the ice giants like Neptune and Uranus. This however is not true of other stars. Many stars have large planets very small orbits.
The inner planets are the four planets nearest to the sun. They are Mercury, Venus, Earth and Mars. They all have rocky surfaces, they all orbit the sun much quicker than the outer gas giants. They are all warmer than the outer gas giants. They are all between the asteroid belt and the sun.
There are a lot of differences between the inner and outer planets. First of all, they inner planets are also known as the "Rocky planets". THey are rocky, hence their name "Rocky planets". And the outer planets are also known as "Gas Giants." THey are mainly composed of gas, hence their name, "Gas Giants." Another difference is their mass. The outer planets have greater mass than the inner planets. In other words, they are heavier.The inner planets follow orbital paths which, like those of the outer planets,are centered on the sun. But the inner planets, without exception, are nearerto the sun than any of the outer planets are.
The outer planets have rings and satellites And Inner planets are called terrestrial planets because they are rocky. (Like Earth.) and receive more of the sun's energy so they have higher temperatures
The compositions of the inner planets and outer planter are nickel, iron, and rock formations. Some of the gases are methane and ammonia and water.2nd Answer:The 'inner' planets, better called, "Terran" planets (Earth is Terra) are solid per the above answer. The 'outer' planets, better called, "Jovian" planets (Jove is a more 'English' form of Jupiter) are all gas giants - they are not solid, although some think that their cores might be rocky.
The inner planets are all rocky planets, whereas the outer planets are gas giants. Pluto is the exception. The outer planets also make 99% of our planets and are outside the asteroid belt.
Inner planets orTerrestrial Planets Mercury, Venus, Earth and Mars are the "Inner" planets (as they are inside the asteroid belt), but are also called the terrestrial planets, as they are primarily composed of rock and metal.Mercury, Venus, Earth, and Mars are all inner planets.
