argumentOfPeriapsisreadonly

argumentOfPeriapsis: number

Argument of periapsis, radians.

ascendingNodereadonly

ascendingNode?: number

Longitude of the ascending node, radians, where it is published.

The eight planets and the twenty moons leave this out on purpose — the header explains why a satellite's node is not a fact a player can check. A small body's is: JPL publishes an osculating element set for every one of them, and where Halley is on its orbit in 2061 is a thing somebody will look up. Absent means "draw it from the seed", which is what every body in bodies.ts does.

atmospherereadonly

atmosphere: SolarAtmosphere | null

axialTiltreadonly

axialTilt: number

Obliquity to the orbit, radians.

cloudsreadonly

clouds: SolarClouds | null

discoveryYearreadonly

discoveryYear: number

Discovery year; 0 for the six known since antiquity.

eccentricityreadonly

eccentricity: number

figurereadonly

figure: BodyFigure | null

The measured figure, for a body gravity never rounded off.

Null means round, not unknown. See BodyFigure; the half-extents here are JPL's published extent halved, and the model keys name files in data/shapes/.

geometricAlbedoreadonly

geometricAlbedo: number

Geometric albedo.

hazereadonly

haze: SolarHaze | null

inclinationreadonly

inclination: number

Inclination to the parent's equator (moons) or the ecliptic (planets).

kindreadonly

kind: BodyKind

massreadonly

mass: number

meanAnomalyreadonly

meanAnomaly?: number

Mean anomaly at J2000, radians, where it is published. See ascendingNode.

moonsreadonly

moons: readonly SolarBody[]

namereadonly

name: string

polarRadiusreadonly

polarRadius: number

Polar radius. Equal to radius for a body with no measured flattening.

radiusreadonly

radius: number

Equatorial radius — the largest half-extent a for a body that is not round.

reliefreadonly

relief: number

Peak-to-trough relief the elevation map covers, meters.

ringsreadonly

rings: SolarRings | null

rotationPeriodreadonly

rotationPeriod: number

Sidereal rotation period. Negative is retrograde.

roughnessreadonly

roughness: number

semiMajorAxisreadonly

semiMajorAxis: number

Semi-major axis about the parent.

temperaturereadonly

temperature: number

Mean surface or 1-bar temperature, kelvin.

texturereadonly

texture: string | null

Texture-set key, or null where no map has been vendored.

tintreadonly

tint: LinearRgb

Linear-sRGB tint applied to the albedo map, or the whole surface without one.

Not decoration. The USGS Voyager and Galileo mosaics for Europa, Ganymede and Callisto are monochrome — measured: zero saturation across all three — because that is how those cameras returned them. Rendering them gray would be a different lie from tinting them: the colors here are the published ones, and the map supplies the structure it actually has.
