Which orbit type abbreviation is correctly matched with its full name?

• A. GEO - Geostationary Earth Orbit
• B. MEO - Low Earth Orbit
• C. LEO - Medium Earth Orbit
• D. HEO - High Earth Orbit

Answer: (A)

Understanding orbit abbreviations helps you map a satellite’s path to its typical altitude and behavior. Geostationary describes a special case where the satellite’s orbital period equals Earth’s rotation, causing it to stay fixed over a point on the equator. That exact property is what the abbreviation GEO denotes when expanded as Geostationary Earth Orbit, so it’s the correct match here. The other pairings don’t align with standard names: MEO is actually Medium Earth Orbit (not Low); LEO is Low Earth Orbit (not Medium); HEO is typically Highly Elliptical Orbit (not High Earth Orbit). So GEO -> Geostationary Earth Orbit is the correct expansion.
