Which orbit type abbreviation is matched to "Low Earth Orbit" in the material?

Which orbit type abbreviation is matched to "Low Earth Orbit" in the material?

• A. GEO
• B. MEO
• C. LEO
• D. HEO

Answer: (C)

The key idea is matching the orbital regime with its standard abbreviation. Low Earth Orbit refers to satellites that stay relatively close to Earth, typically up to about 2,000 kilometers above the surface. The abbreviation that represents this regime is LEO, short for Low Earth Orbit. The other abbreviations correspond to different regimes: GEO is Geostationary Orbit, far above Earth at about 35,786 kilometers with a 24-hour orbital period; MEO stands for Medium Earth Orbit, at intermediate altitudes roughly from 2,000 to 20,000 kilometers; HEO means Highly Elliptical Orbit, which is elongated and spends time at high altitudes. Since Low Earth Orbit is specifically named by the abbreviation LEO, that is the correct match.
