π Physics in the Sky: How Satellites Stay in Orbit
π What Does It Mean?
Satellite Orbit: An orbit is a curved path that a satellite follows around a planet due to the balance of two forces: gravity pulling it inward and its motion trying to move it forward.
π‘ Applications of Satellite Orbits
- π Communication: Mobile, internet, and TV signal transmission
- π°️ GPS Navigation: Helps with maps and location tracking
- π· Earth Observation: For weather forecasting and disaster monitoring
- π Space Science: Telescopes in orbit like Hubble for astronomy
π‘ Real-Life Examples
- π°️ International Space Station (ISS): Orbits Earth every 90 minutes
- π°️ Geo-stationary Satellites: Stay fixed over one point on Earth
- π°️ Starlink Satellites: Provide internet from space
✅ Advantages of Satellite Orbits
- π Wide coverage of the planet
- π Real-time data collection and communication
- π‘ Minimal infrastructure needed on Earth
⚠️ Disadvantages of Satellite Orbits
- πΈ High cost of launch and maintenance
- π₯ Risk of collision or space debris
- π«️ Signal delays or loss in bad weather
