This is not really a "why" question. 20 years ago, we thought gas giants couldn't form close to stars; we've since found that "Hot Jupiters" (large gas giant planets orbiting close to their stars) are fairly common. There's no theoretical reason we know of that couldn't have happened in our solar system as well, it simply didn't.
Heres my hypothesis. The closer the planet to the sun, the stronger the gravity, therefore heavier materials are able to be attracted, when the sun was formed, a ring of dust existed around it and this ring congealed into planets, in the dust cloud the heaviest and densest materials were closer to the sun, therefore, when this material became planets, these areas formed the densest planets.
Early on in the solar systems formation, rock and metals condensed out at the higher temperatures closer to the sun, forming the terrestrial or rocky inner planets, while gas and water tended to condense further out, forming the gas giant planets.
Although the gas giants are larger than the inner planets, they are mainly made of Helium and Hydrogen gas, while the inner planets are mainly made from more dense materials such as rock.
becasue it is near to the sun compared to the outter planets
There are examples of extrasolar systems where gaseous giants form close to a star as well. By chance ours is set up this way.
yes
the inner orbit faster
the inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}
The distances between the inner planets is smaller than the distances between the outer planets.
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
One major difference is their size. Pluto is significantly smaller than the solid inner planets like Earth, Mars, Venus, and Mercury. Another difference is their composition. Inner planets are primarily composed of rock and metal, while Pluto is composed mostly of ice and rock. Additionally, inner planets have clear and defined orbits around the Sun, while Pluto's orbit is more eccentric and tilted.
Inner planets
Inner planets are mostly rock and outer planets are mostly gas.
the inner orbit faster
i dont knoww
Each of the four inner planets have a clearly defined terrain. They are different to the gas planets, which don't have a clear solid surface. The inner planets are also much smaller and less massive, yet have a higher density than the outer planets. The inner planets have fewr moons due to their smaller mass and size. As they are closer to the sun, they orbit the sun in less time and are also warmer.

The inner planets are closer together than the outer planets are.
The size. The gaseous Jovian planets are far larger than the inner terrestrial planets.
Location, location, location. Inner planets = Mars and inward (towards the sun); outer planets = Jupiter and outward (away from the sun).
The distances between the inner planets is smaller than the distances between the outer planets.
