Low Earth Orbit

Low Earth Orbit (LEO) refers to a region of space that is relatively close to Earth, typically ranging from about 100 to 2,000 kilometers (62 to 1,240 miles) above the planet's surface. Satellites in LEO orbit the Earth quickly, completing a full revolution in about 90 to 120 minutes. This proximity allows for lower latency in communications and easier access for missions, making LEO popular for satellites used in telecommunications, Earth observation, and space research. Notable examples include the International Space Station (ISS) and many modern communication satellites.
