Categories of Earth Orbits

Let’s explore the different Earth orbits and their interpretations in this table:

Orbit Type Range Earth Orbit Velocity Interpretation
Low Earth Orbit 99 – 1,200 miles √(6.67430 x 10^-11 m^3/kg/s² * 5.972190 x 10^24 kg / (6,371,000 m + 160,934 m)) The swift dance of satellites and the ISS.
Geostationary Orbit 22,236 miles √(6.67430 x 10^-11 m^3/kg/s² * 5.972190 x 10^24 kg / (6,371,000 m + 35,786,000 m)) Where communication satellites stay put.
Polar Orbit Varies √(6.67430 x 10^-11 m^3/kg/s² * 5.972190 x 10^24 kg / (6,371,000 m + altitude)) A bird’s-eye view for Earth observation.
