What it is Filled
A giant planet composed mainly of hydrogen and helium, without a solid surface, such as Jupiter and Saturn; exoplanet gas giants include hot Jupiters and cold Jupiters, while super-Neptunes qualify only if their composition is predominantly hydrogen and helium.
Why it exists Filled
Let an agent describe gas giants by example, composition, structure and detection, with sourced data.
Distinguishing features Filled
- Mostly hydrogen and helium
- No solid surface
- Many moons and rings
- Common among exoplanets detected
What robots and AI may and may not do Filled
Must not
- Present a candidate exoplanet as confirmed before it has been confirmed.
- Overstate the chance of life on or around a gas giant without evidence.
- Misattribute discoveries to the wrong team or instrument.
Only with a human decision
- Announcing a new discovery to the public on behalf of a research team.
May
- Describe gas giants and their properties from observational data with sources.
- Classify a planet as a gas giant and state the uncertainty of mass and radius estimates.
Moral aspects Filled
- Public trust in science depends on honest reporting of what is confirmed and what is not.
- Credit for discoveries should go to the people and teams who made them.
Who is affected
- The public and learners
- Researchers and observatories
Owners Filled
Steward
Nobody: celestial bodies belong to no one under the Outer Space Treaty; astronomers study them.
