Which type of satellites orbit planets?

Satellites that orbit planets can be categorized into two types: natural satellites and artificial satellites. Natural satellites are celestial bodies, such as moons, that form through natural processes and exist in orbit around their parent planet. For instance, Earth's Moon is a natural satellite that has been forming and orbiting our planet for billions of years.

On the other hand, artificial satellites are man-made objects launched into orbit for various purposes, including communication, weather monitoring, and scientific research. Both types of satellites play significant roles in our understanding of space and in the functioning of technology on Earth.

This understanding leads to the conclusion that both natural and artificial satellites can orbit planets, making the first choice the correct answer. The other options fail to account for this duality: they either suggest that only one type of satellite exists or that no satellites orbit planets at all, which is not accurate.
