    Index
    albedo atmosphere axialTilt colors gm index kind name orbit parent parentIndex radius rings rotationAtEpoch siderealDay surface temperature tidallyLocked
    albedo: number

    Bond albedo, 0..1 (moons: how bright the lit disc is).

    atmosphere: BodyAtmosphere | null

    Optional atmosphere glow in the solar-system view.

    axialTilt: number

    Obliquity: tilt of the spin axis from the orbit's reference plane, degrees.

    colors: [string, string, string]

    Three surface colours for the procedural style (#rrggbb).

    gm: number

    Gravitational parameter GM, m³/s² (the mass that children orbit).

    index: number

    Index in StarSystem.bodies.

    kind: BodyKind

    Star, planet or moon.

    name: string

    Unique name. The defaults are 'sun', 'home' and 'moon'.

    orbit: OrbitalElements | null

    Orbit around parent; null for the central star.

    parent: string | null

    Name of the body it orbits; null for the central star.

    parentIndex: number

    Index of the parent, or -1.

    radius: number

    Mean radius, metres.

    rings: RingOptions | null

    Optional rings.

    rotationAtEpoch: number

    Spin angle at the J2000 epoch, degrees.

    siderealDay: number

    Rotation period relative to the stars, seconds. Negative spins retrograde, 0 doesn't spin.

    surface: SurfaceStyle

    Procedural surface style for the solar-system view.

    temperature: number

    Black-body temperature, kelvin (stars: sets the light colour).

    tidallyLocked: boolean

    Always shows the same face to its parent (spin follows the orbit).
