- Artificial: Satellites are man-made objects designed and launched into space for a specific purpose.
- Orbiting: Satellites orbit around a celestial body, such as the Earth or the Moon, in a predetermined path.
- Altitude: Satellites can be placed in different altitudes, depending on their purpose. Low Earth orbit (LEO) satellites are typically at an altitude of 1,200 to 2,000 kilometers, while geosynchronous orbit (GEO) satellites are at an altitude of 35,786 kilometers.
- Size: Satellites can range in size from a few centimeters to several meters, depending on their payload and purpose.
- Shape: Satellites can have a variety of shapes, including cylindrical, conical, or spherical.
- Power source: Satellites typically rely on solar panels or batteries to generate power for their systems.
- Communications: Many satellites are used for communication purposes, such as transmitting data, phone calls, or television signals.
- Surveillance: Satellites can be used for surveillance and observation, such as monitoring weather patterns or collecting data on the Earth’s surface.
- Scientific research: Some satellites are used for scientific research, such as studying the Earth’s atmosphere or observing celestial objects in the universe.
