Question

astronomy: orbital motion unit test a satellite that is in geosynchronous orbit around earth.... (1 point) orbits earth once every 24 hours, matching earths rotation orbits earth once every 12 hours has a highly elliptical orbit must be placed at low earth orbit (below 8,400 km)

Explanation:

A geosynchronous satellite orbits Earth with a period that matches Earth's rotational period (24 hours), so it appears stationary relative to a point on Earth. The other options are incorrect: a 12 - hour orbit doesn't match rotation, geosynchronous orbits are nearly circular (not highly elliptical), and geosynchronous orbits are at high altitudes (not low Earth orbit).

Answer:

A. Orbits Earth once every 24 hours, matching Earth's rotation
