A geostationary satellite orbits Earth at a height where its period equals

1. A geostationary satellite appears fixed above a point on Earth's equator. 2. Its orbital period must equal Earth's rotation period ≈ 24 hours. 3. Orbital altitude works out to about 35,786 km above the surface. 4. It orbits in the equatorial plane in the same direction as Earth's rotation. _Source: syllabus Physics, Ch 7 "Gravitation", §7.6_
