A satellite with an orbital period the same as the Earth's rotation period. Geostationary satellite. A geostationary satellite orbits Earth at the same speed as Earth's rotation, making it appear stationary over one spot.
Imagine you're trying to walk on a moving walkway at the airport, keeping pace perfectly so that you stay beside a friend standing on the stationary ground. This is similar to how a geostationary satellite orbits the Earth, matching the planet's rotation so it stays above the same spot on the surface. Just as you adjust your walking speed to move alongside your stationary friend, the satellite adjusts its orbital speed to match the Earth's rotation period, ensuring it remains fixed above one geographical location.
