They tend to be round, spherical objects which are visible in space. They have great mass and their own gravity.
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.
anyway they are alike because they have the rotation around the sun, and that is what gives them time to go around!! And there are four planets each, and they are all plantes(; haha
The inner and outer planets are alike in that they are all part of our solar system and orbit around the Sun. They also have varying sizes and compositions, with the inner planets being smaller and rocky while the outer planets are larger and gaseous. Additionally, they all have moons, but the outer planets tend to have more and larger moons compared to the inner planets.
They are alike because they are all planets and they orbit around the same star (the Sun.) They are also in the same solar system.
they are alike in the way that they are solid not gaseous and that they are relitivly small.
Inner and outer planets are both part of the solar system, but they differ in composition and location. Inner planets are rocky and located closer to the sun, while outer planets are gas giants and located farther away. Both sets of planets have natural satellites, but the outer planets tend to have more moons.
Venus and Earth are the most alike in terms of size, composition, and proximity to the sun. Both planets have similar densities and rocky surfaces. Venus is often referred to as Earth's "sister planet" due to these similarities.
None of the inner planets are alike - they are all different in their own sweet way.
their all gas planets
They're both planets.
The answer depends on which planets "these" refers to.
They all have alike materials and rocky cores.
