Final answer:
The characteristic or pattern of the planets that is NOT used for modeling the formation process of the solar system is D. All the planets orbit within the magnetosphere of the Sun.
Step-by-step explanation:
The characteristic or pattern of the planets that is NOT used for modeling the formation process of the solar system is D. All the planets orbit within the magnetosphere of the Sun.
While the other options are characteristics or patterns of the planets used for modeling the formation process of the solar system, the distribution of the chemical elements among the planets is particularly important in understanding the formation and composition of the planets.
