Satellite Leo refers to low Earth orbit (LEO) satellites that orbit the Earth at an altitude of around 2,000 kilometers. These satellites are used for various purposes such as communication, Earth observation, and scientific research. LEO satellites have shorter orbital periods and are closer to Earth compared to other types of satellites, which can result in faster data transmission and lower latency.
The time it takes for a satellite to complete one full orbit around the Earth, known as its orbital period, can vary depending on the altitude of the satellite. On average, a satellite in low Earth orbit (LEO) typically takes about 90 minutes to complete one orbit, while a geostationary satellite orbits the Earth every 24 hours.
The orbital speed of a low Earth orbit (LEO) satellite, typically at altitudes around 200 to 2,000 kilometers, is approximately 7.8 kilometers per second (about 28,000 kilometers per hour or 17,500 miles per hour). This speed allows the satellite to balance gravitational forces and maintain a stable orbit around the Earth. Variations in altitude can slightly affect this speed, but it generally remains within this range for LEO satellites.
Satellites in Low Earth Orbit (LEO) must travel fast to continue orbiting the Earth without falling back down due to gravity. The high speed helps to balance the force of gravity to keep the satellite in orbit. Additionally, the fast speed allows the satellite to complete its orbit around the Earth in a relatively short amount of time.

LEO orbit is closer to the Earth than a geostationary orbit is.There's essentially no difference in their distance from the Sun.
The time it takes for a satellite to complete one full orbit around the Earth, known as its orbital period, can vary depending on the altitude of the satellite. On average, a satellite in low Earth orbit (LEO) typically takes about 90 minutes to complete one orbit, while a geostationary satellite orbits the Earth every 24 hours.
That is the exact questin i had!!

umm if my calculations are correct the period of a low earth orbit (LEO) is approximately 40000000000069 years. as extrapolated from Kepler's equation.

no,I have tryed,to become friends with people but they are not ready.
The best kind of orbit for a military spy satellite is typically a low Earth orbit (LEO), usually between 180 to 2,000 kilometers above the Earth. This orbit allows for high-resolution imaging and better surveillance capabilities due to its proximity to the surface. Additionally, LEO satellites can revisit targets more frequently, enhancing real-time intelligence gathering. Geostationary orbits may also be used for continuous coverage, but they are less effective for detailed imaging compared to LEO.
LEO os called Low earth orbit, MEO is called Medium Earth Orbit and GEO is called Geostationary orbit. LEO are about 500 Km to 1500 Km above the earth, so the delay is very small and the losses is small too. MEO are installed at 5000 to 12000 km above the earth and generally used for navigation communications like GPS. GEO is about 35800 Km above the equator, the delay and losses are greater, but the advantages is more coverage (it covers 40% of the earth) and there no need to track the satellite, so the earth terminal is cheaper.See the following figure which describes them nicelyI would like to add few additional information as follows:1. Since LEO satellite is nearer to planet compare to MEO and GEO, it has small cell (or foot print).2. Due to small cell coverage, more number of LEO satellite need to install to cover the planet(for instance earth).3. LEO moves very fast compare to MEO, so very frequent hand-off is required between two LEO satellites to avoid interrupt for ongoing calls between two users.4. GPS satellite uses medium earth orbit.5. Satellites which use geostationary orbit known as GEO
