SSC CGL 2025 Tier 1 Question Paper (25-Sep-2025) (Shift 3)
The correct answer is

Appears stationary

A satellite that orbits the Earth with a period of exactly 24 hours, matching Earth's own rotation period, moves in sync with the planet's rotation.

When such a satellite is placed in orbit directly above the equator at the appropriate altitude, it appears to remain fixed over a single point on the Earth's surface, a condition known as being geostationary.

This is precisely why geostationary satellites, orbiting at about 36,000 km altitude, are so useful for continuous communication and weather monitoring, since ground stations do not need to track their movement.

Hence, the answer is Appears stationary.
