**Difference between Natural Satellite and Man-made Satellite**

A satellite is an object that revolves around a larger celestial body, such as a planet or a star. Satellites can be broadly categorized into two types: natural satellites and man-made satellites.

**Natural Satellites:**
Natural satellites are celestial bodies that orbit around a planet or any other astronomical object. The most well-known natural satellite is Earth's moon. Other examples of natural satellites include the moons of other planets in our solar system, such as Mars' moons Phobos and Deimos, Jupiter's largest moons like Ganymede and Callisto, and Saturn's moon Titan.

**Characteristics of Natural Satellites:**
1. Formation: Natural satellites are formed through various processes. Some are remnants of the formation of the planet they orbit, while others are captured asteroids or comets.
2. Size and Shape: Natural satellites come in various sizes and shapes. They can range from small rocky bodies to large icy worlds.
3. Gravity: Natural satellites have their own gravitational force, which allows them to stay in orbit around the celestial body they are associated with.
4. Composition: The composition of natural satellites varies depending on their origin. Some may have rocky surfaces, while others may be composed of ice or a combination of both.

**Man-made Satellites:**
Man-made satellites, also known as artificial satellites, are human-made objects that are intentionally placed into orbit around the Earth or other celestial bodies. These satellites serve various purposes, such as communication, weather monitoring, navigation, scientific research, and military surveillance.

**Characteristics of Man-made Satellites:**
1. Design and Launch: Man-made satellites are designed and constructed by humans. They are launched into space using rockets and other space vehicles.
2. Size and Shape: Man-made satellites come in different sizes and shapes depending on their intended purpose. They can be as small as a shoebox or as large as a school bus.
3. Technology: Man-made satellites are equipped with advanced technology, including communication systems, cameras, sensors, and scientific instruments, depending on their specific missions.
4. Lifespan: The lifespan of man-made satellites can vary. Some satellites are designed for short-term missions, while others are built to operate for several years.

**Conclusion:**
In summary, natural satellites are celestial bodies that naturally occur and orbit around a planet or other astronomical objects, while man-made satellites are human-made objects specifically designed and launched into space for various purposes. Natural satellites are formed through natural processes, have their own gravitational force, and come in various sizes and compositions. On the other hand, man-made satellites are designed by humans, equipped with advanced technology, and serve specific functions based on their missions.
