The time period of revolution of a geostationary satellite is: MCQ with Answer and Explanation

The time period of revolution of a geostationary satellite is:
A. Variable
B. 84 minutes
C. 12 hours
D. 24 hours
Answer: Option D
Solution (By JKSSB Mock Tests)
Geostationary satellites orbit in Earth's equatorial plane with period matching Earth's rotation period (24 hours), so they appear stationary relative to ground. Orbital radius is about 42,000 km from Earth's center. Memory tip: 'Geostationary: T=24 h, equatorial orbit, fixed position; used for communication/weather satellites'. This standard result is frequently tested in competitive exams. Always recall that geostationary is a special case of geosynchronous (same period) with zero inclination; competitive exams often compare low orbit (84 min) vs geostationary (24 h) periods.
