The theory explaining planetary formation was ideated in the late 19th century. It's true that it has undergone a lot of modification since then to include what we've learned through observation and a bit of calculation. But the center of the idea is that at some point in time, gaseous components in a molecular cloud or nebulosity are pulled together and concentrate due to gravity. Then a long period of accretion sees the formation of a star and an associated planetary system. This is the nebular hypothesis.
As more and more time passes, enough material "clumps together" that a gravity well forms and "gathers" all the material in the vicinity. Separate gravity wells "stake claim" to volumes of space around a central point where a star forms. Eventually, enough material gathers and gravity becomes high enough to form everything into a sphere, as planets are shaped in a ball because it is the most efficient response to that much gravity.

it is a hard formula
What else can I help you with?
Why are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.
What are the planets made of gas called?
Planets made mostly of gas are called gas giants. These planets have a thick atmosphere composed primarily of hydrogen and helium, with a small solid core at their center. Examples include Jupiter and Saturn in our solar system.
What do terrestrial planets and jovian planets have in common?
Terrestrial planets and jovian planets are both types of planets found in our solar system. They are made up of different materials - terrestrial planets have solid surfaces predominantly made of rock and metal, while jovian planets are primarily composed of gas and liquids. Both types of planets orbit a star and have moons or natural satellites.
What are two major differences in the composition of the inner and outer planets?
the inner planets are rocky and warm and the outer planets are made out of gas and is cold
Are all planets made of the same substances?
NO
What planets are rock planets that the just the planets core made from rock?
there are 9 planets
How do the inner planets diffrer from the outer planets?
the inner planets made up of rocks while the outer planets are made up of gases and liquids.
What three planets are made of mass?
All the planets are made of "matter" and that has "mass".
What planets are just made of gases?
Type your answer here... all planets are made of gasses
What planets is made of rocks?
The planets Mercury, Venus, Earth, and Mars are made of rock.
Why are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.
Are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.
Are planets organic?
No. The planets are made primarily of inorganic substances.
Are the inner planets large planets made up of mostly gas?
No, those are the outer planets.
How are the otter planets different from inner planets?
yes the outer planets are made of gas and liquids.
Is outer planets made of heavier material than a inner planet?
No because the inner planets are made of rocky and hard substances and the outer planets are made of gassy lighter substances.
What are the characteristics of outer and inner planets?
The inner planets are the first 4 planets from the sun, they are made of rock. After the in er planets is an asteroid belt. Behind the belt are the 4 outter planets. They are made of gas and are called "gas giants". These are called outter planets.
