What is Low Earth Orbit?

Low Earth orbit (LEO) is a type of orbit that is close to the Earth's surface. In general, a low Earth orbit is an orbit that is less than 2,000 kilometers (1,200 miles) above the Earth's surface. At this altitude, the Earth's gravitational pull is still strong enough to keep objects in orbit, but the objects are close enough to the Earth's surface to interact with it in various ways.

Low Earth orbits are commonly used for satellites that provide services such as telecommunications, weather forecasting, and remote sensing. These satellites are able to orbit the Earth quickly, allowing them to collect and transmit data on a regular basis.

Low Earth orbits are also used by the International Space Station and other spacecraft that carry astronauts and other crew members. At these altitudes, the spacecraft can easily access the Earth's atmosphere and make use of its resources, such as oxygen and water.

Overall, low Earth orbit is a critical part of space exploration and satellite-based services, and it continues to play an important role in our understanding and use of space.
