Question

Quizplus · Accepted Answer

The Earlybird communication satellite hovers over the same point on Earth's equator indefinitely because its orbital period is 24 hours, which is the same as the Earth's rotational period. This means that the satellite maintains the same relative position above the Earth's surface as the Earth rotates on its axis, giving the appearance that the satellite is stationary. This is known as a geostationary orbit.
