What describes a near-polar orbit?

A near-polar orbit is characterized by its alignment with the Earth's poles, allowing an orbiting satellite to pass over or near the North and South poles. This type of orbit typically has a high inclination, usually around 90 degrees, which enables the satellite to cover almost the entire surface of the Earth over time. As the Earth rotates beneath the satellite, the orbits gradually shift, allowing for comprehensive coverage of different regions, which is particularly useful for applications like environmental monitoring, mapping, and reconnaissance.

The key attribute of a near-polar orbit is its constant elevation, which maintains a stable distance from the Earth's surface as it moves directly above the poles. This ensures consistent observation capabilities from the satellite across various latitudes. In contrast, other choices describe different types of orbits or scenarios that do not accurately capture the essence of a near-polar orbit. For instance, an orbital path that remains close to the equator pertains to geostationary orbits, while variable elevations refer to highly elliptical orbits or other specialized orbits not aligned with the poles. Lastly, while weather satellites use polar orbits, not all near-polar orbits are dedicated to weather observations, making that description overly restrictive.
