Wonder: Why are planets in our solar system made of different material
Obviously we don’t know the exact answer to the question, but we have a pretty good idea. Firstly when our solar system was being form their was these clouds called molecular clouds that were made of mainly hydrogen and dust. These clouds started to spin really fast, concentrating most of the material in the middle. These material started to form rocks and metal and started to warm up. This soon became the sun and when it was “born” it still collected more material. Then the ice, other rocks and other material started to form the inner planets like mars and earth. Eventually the sun had to get rid of the excess material so it released it in these this called solar winds and it push these material, gas and the atmosphere from the inner planets to the outer planets. These planets were mainly formed from the hydrogen and helium from the sun and the ice that couldn’t go to close to the sun or it would melt. The outer planets started to grow with the solar winds and the atmosphere which had hydrogen and helium into it and it had a higher gravitational pull with pull the materials out to them which also made them bigger then the inner planets. So that is one explanation to the question Why are planets in our solar system made of different material.
