The key characteristic of a geostationary orbit is that it allows satellites to remain over the same point on the Earth's surface. This is achieved by positioning satellites at an altitude of approximately 35,786 kilometers (about 22,236 miles) above the Earth's equator. In this orbit, the satellite moves in sync with the Earth's rotation, completing one orbit in 24 hours, which is the same duration it takes for the Earth to rotate once on its axis.

This synchronous orbit is particularly beneficial for weather satellites like GOES (Geostationary Operational Environmental Satellites), as they can provide continuous monitoring and data collection of specific areas. The ability to maintain a fixed position is crucial for various applications, including weather forecasting and disaster monitoring, where consistent observation of specific regions is essential.

The other options describe characteristics that do not align with the nature of a geostationary orbit. For example, a geostationary orbit is circular, not highly elliptical, and is located at a significant altitude rather than a very low one. Additionally, perigee refers to the point in an elliptical orbit closest to the body being orbited, which does not describe the consistent nature of a geostationary orbit. Thus, the defining feature
