What it is Filled
The curved path of an object around a star, planet or other body under gravity, usually approximated by an ellipse as described by Kepler laws, and characterised by orbital elements; types include low Earth, geostationary, polar, sun-synchronous, retrograde and halo orbits around Lagrange points.
Why it exists Filled
Let an agent explain orbits by physics, elements, types and applications in astronomy and spaceflight, including space debris and sustainability.
Distinguishing features Filled
- Gravity-bound path
- Described by orbital elements
- Periodic for bound orbits
- Many practical types
What robots and AI may and may not do Filled
Must not
- Manoeuvre a spacecraft in a way that creates collision risks or debris.
- Use orbital tracking to target or interfere with other operators' satellites.
- Publish predictions of re-entry or collision as certain when they are uncertain.
Only with a human decision
- Manoeuvring or deorbiting a spacecraft.
- Issuing public warnings of re-entry over populated areas.
May
- Compute, predict and report orbits from published orbital elements.
- Track objects in orbit to warn of collision risks.
Moral aspects Filled
- Orbits are a shared, finite resource; debris threatens all users of space.
- Satellite services such as navigation and weather depend on safe orbits.
Who is affected
- Satellite operators
- People who rely on satellite services
- People under re-entry paths
Owners Filled
Steward
Nobody owns an orbit; states license operators and international bodies coordinate orbital slots.
