In terms of cosmic structure, what is the relationship between natural satellites and planets?

The relationship between natural satellites and planets is best described by the fact that natural satellites orbit planets. In our solar system, for instance, moons are natural satellites that are held in orbit around larger bodies, which are the planets. This relationship is a result of gravitational forces, where the mass of the planet exerts a pull on its satellite, keeping it in a stable orbit.

In contrast, the other options do not accurately describe the interactions between natural satellites and planets. Planets do not orbit natural satellites since the satellites are much smaller and dependent on their host planet for their gravitational binding. While both planets and their satellites, along with other celestial bodies, do orbit the Sun as part of the broader dynamics of the solar system, this does not specifically reflect the direct relationship between the two. Additionally, stating that neither is orbited by anything would overlook the significant gravitational interactions taking place within the solar system. Thus, option A captures the correct dynamic effectively, establishing the natural satellite as the body that orbits a planet.
