Well Mercury is about 650ºC I think and a boiling pool of magma, whereas Pluto is close to -250ºC and is basically just gas. On the other hand Earth supports life, whereas Jupiter is a cloud of massive storms. It really depends on what you really mean by least alike.
They least resemble rocky planets like Venus Earth and Mars, particularly they least resemble planets that we would consider as possible life sustaining planets.
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.
The Earth and Venus.
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. The inner planets all have a clear solid surface, unlike gaseous planets. The inner planets do not have a ring system. The inner planets are of similar densities.
Mercury is the smallest planet in the Solar System
they are alike in the way that they are solid not gaseous and that they are relitivly small.
None of the inner planets are alike - they are all different in their own sweet way.
The answer depends on which planets "these" refers to.
their all gas planets
They're both planets.
They all have alike materials and rocky cores.
Both have rings and are outer planets.
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.
both planets
they are both planets
earth and venus are alike because they are both on the inner planets
they are both planets
