1. Composition of the planets: The different planets in our solar system have varying compositions, with the inner planets being rocky and the outer planets being gas giants. This suggests that the planets formed in different regions of the solar nebula.
2. Orbits of the planets: The orbits of the planets around the Sun are often cited as evidence for the formation of the solar system from a spinning disk of gas and dust. The planets all orbit in a fairly flat plane, with the same direction of rotation, which is consistent with the idea of a rotating protoplanetary disk.
3. Asteroid and comet composition: The composition of asteroids and comets in our solar system can provide clues about the early stages of planet formation. For example, the presence of water and organic molecules in comets suggests that they formed in the outer regions of the solar system, beyond the "snow line" where water and other volatile compounds could condense.
4. Meteorites: By studying meteorites that have fallen to Earth, scientists can learn about the early history of the solar system. Some meteorites contain isotopic signatures that suggest they formed very early in the solar system's history, before the planets had fully formed.
5. Observations of other star systems: By studying other star systems, astronomers can gain insights into the processes that lead to planet formation. Many exoplanet systems have been found to have planets in similar configurations to our solar system, supporting the idea that our own system formed through a similar process.
