A possible example of a rock similar in composition to the material that formed planets is chondrite meteorites. These rocks contain minerals and components that are indicative of the early solar system, providing valuable insights into the processes that led to planet formation. Chondrites are thought to represent some of the most primitive material in our solar system.
They were made of dust, not rock
there are 9 planets
It's because each planets is a collection of all the debris that was going round in a similar orbit before the planets were formed. So the planets only survived to the present day by having different orbits.
The rock that makes up the planets is primarily composed of silicate minerals such as quartz, feldspar, and mica. These minerals form from the cooling and solidification of molten rock, or magma, that was present in the early solar system. Additionally, rocks in the planets may contain other elements like iron, nickel, and carbonates.
A meteorite is a piece of rock that is similar to the material formed into planets. Meteorites are remnants from the early solar system that can provide insights into the processes that formed the planets.
Soil (no rocks)
Asteroids are pieces of rock that are similar in composition to the material that formed the planets in our solar system. They are remnants from the early stages of solar system formation and can provide clues about the processes that led to the formation of planets.
There are lots of different types of rocks that form the planets.

All inner planets are made of rock. (Earth, Mars, Venus, and Mercury)
Obviously they formed in the same manner...Gravity is Gravity!
The four inner planets are all made of rock or are rock based but the four outer planets are all made of gas or gas based.
They were made of dust, not rock
It is a cosmic body, formed from a cloud of dust and gases.
Inner planets are rock with minerals similar to those on Earth
Venus and Earth have similar compositions, both being terrestrial planets with rocky surfaces. They also have similar densities, indicating similar compositions of silicate rock and metal elements.
