Geostationary satellites orbit the Earth at an approximate altitude of 36,000 kilometers (about 22,236 miles). At this height, satellites orbit the Earth at the same rate that the Earth rotates, allowing them to remain stationary relative to a fixed point on the surface, which is crucial for consistent communication and weather monitoring services.
