Geostationary Orbit:

• T = 24 hours (same as Earth's rotation)
• Height ≈ 35,786 km above surface
• In the equatorial plane
• Angular velocity = Earth's angular velocity
• Appears stationary from Earth (used for communication satellites)

Polar Orbit:

• Passes over both poles
• T ≈ 100 min (low Earth orbit)
• Height ≈ 800-1000 km typically
• Covers the entire Earth surface over multiple orbits
• Used for weather/mapping satellites

Neither orbit depends on satellite mass — only the radius and time period are related through Kepler's third law.
