A natural satellite, also known as a moon, is a celestial body that orbits a planet or a smaller body that orbits a larger one. Moons are abundant in our solar system, with each planet having its own set of natural satellites. The Earth's moon, for example, is a natural satellite that orbits our planet.

Formation

Natural satellites can form in a variety of ways. Some moons are thought to have formed from the same gas and dust cloud that surrounded their parent planet during its formation. Others may have been captured by a planet's gravitational pull, or formed from the debris of a collision between a planet and another celestial body.

Characteristics

Natural satellites come in various sizes and shapes. Some are small and irregularly shaped, while others are large and nearly spherical. Moons can also have unique surface features such as craters, mountains, and valleys. Their surfaces may be rocky, icy, or a combination of both.

Functions

Natural satellites play a crucial role in the dynamics of their parent planets. They can affect the planet's rotation, tides, and even its climate. Moons also provide valuable scientific insights into the history and composition of their parent bodies.
