Geosynchronous Orbits are WEIRD
minutephysics・2 minutes read
Geosynchronous orbits seem motionless from Earth but actually revolve around the planet, enabled by Kepler's laws and distance from the planet affecting orbit time, crucial for communication due to satellites in these orbits maintaining a clear line of sight with the surface, with practicality impacted by altitude.
Insights
- Geosynchronous orbits seem fixed in the sky because they match Earth's rotation, a phenomenon explained by Kepler's laws and orbital distance.
- The practicality of geosynchronous orbits for communication hinges on Earth's rotational speed and the orbital altitude, with deviations causing communication issues.

"Geosynchronous Orbits: Earth's Stationary Communication Satellites"
- Geosynchronous orbits appear stationary from Earth, despite actually orbiting the planet, due to being in sync with Earth's rotation.
- These orbits are made possible by Kepler's laws and the distance from the planet affecting orbit time.
- Geosynchronous orbits are useful for communication purposes, as satellites in these orbits can maintain a clear line of sight with the surface.
- The existence and usefulness of geosynchronous orbits depend on the speed of the planet's rotation.
- The altitude of geosynchronous orbits can impact their practicality, with orbits too close or too far resulting in communication challenges and delays.
