Earth and Venus are close in diameter.
A
terrestrial planet
All of the terrestrial planets are within 1.52 AU of the Sun. All of the gas giants are greater then 5 AU of the sun. The relationship is that most of the terrestrial planets are very close to the sun while gas giants are much further away.
No two planets within our solar system have the same exact size. However, Earth and Venus are quite close - their diameters differ by only 652km.
The terrestrial planets are small in size and mass, they are rocky, solid and dense, all four terrestrial planets have 3 moons between them. They are warm and close to the sun. Terrestrial planets USUALLY have thin atmosphere. The Gas Giants are huge in size, have rings made from dust, debris, ice, rock. They very cold (not close to the sun at all) and light (made from gas.) They have several moons between them (167, I think) and lastly Gas Giants usually have thick and deep atmosphere.
They are called the terrestrial planets because they are similar to Earth (in fact one of them is Earth.
They are too close to the sun to have rings.

Planets are classified into rocky planets (inner planets) and gas giants (outer planets) based on their composition and characteristics. Rocky planets have solid surfaces and are made primarily of rock and metal, while gas giants are mostly composed of hydrogen and helium with thick atmospheres. These distinctions result from differences in how planets formed and the conditions in their respective regions of the solar system.

Durable solids that are very hard to melt and vaporize form close to the Sun, making terrestrial planets.
Gas giants will usually contain all or more of the gasses that a terrestrial planet uses as an atmosphere. But a gas giant will contain massive quantities of gas, and have a core that is made up of gas that is super dense and super heated.
It is my understanding that, due to their close proximity to the Sun, and the corresponding higher temperatures, lighter gases (mainly hydrogen and helium) evaporated off into space.
Mercury is a terrestrial planet because it has a hot climate and it is close to the sun.
They are so large travelling closer to the sun they would have an increased velocity losing there gas to solar winds ect.
