CelestialBody Class
| Inherits | Implements |
|---|---|
| UnityEngine.MonoBehaviour | ITargetable, IDiscoverable |
A CelestialBody represents a planet, moon, or star that acts as a source of gravity and has some sphere of influence. You can find the CelestialBody whose sphere of influence you are currently in with the vessel.mainBody field.

The following are public properties available in CelestialBody.

|---|---|
| DiscoveryInfo DiscoveryInfo { get; } | ? |

| string name { get; } | The name of the body, as it appears in e.g. the map view. Same as bodyName field.
|

Fields
The following is a list of publically-accessible fields in CelestialBody. This includes protected items, which can be accessed by subclasses.
| Signature | Description |
|---|---|

| double hillSphere | ? |
| double initialRotation | ? |
| bool inverseRotation | ? |
| float inverseRotThresholdAltitude | ? |
| double Mass | the mass of the body, in KSP's arbitrary mass units. For calculating gravity, KSP seems to use a gravitational constant of G = 6.674E-11 (SI units), which is the same as the real one rounded to 3 decimal places. |
| double maxAtmosphereAltitude | The height above sea level at which the atmosphere ends, in meters. |
| bool ocean | ? |
| OrbitDriver orbitDriver | ? |
| List<CelestialBody> orbitingBodies | A list of all the bodies that orbit this one (e.g., the moons of a planet) |
| PQS pqsController | An object that can give you information about the planet's terrain height as a function of position. See the documentation on the PQS class to see how to use it. |
| AnimationCurve pressureCurve | Atmospheric pressure by altitude stored as an AnimationCurve. Altitude is in meters stored as Keys. Pressure is in atmospheres stored as Values. Multiplied by pressureMultiplier to determine final pressure for a given altitude. useLegacyAtmosphere must be set to False! |
| float pressureMultiplier | Multiplies atmospheric pressure as determined by pressureCurve when useLegacyAtmosphere is False. |
| double Radius | The radius of the planet in meters. This defines sea level. |
| bool rotates | ? |
| QuaternionD rotation | ? |
| double rotationAngle | The current angle of the body's rotation |
| double rotationPeriod | How long it takes the planet to revolve once about its axis, in seconds. |
| CelestialBodyScienceParams scienceValues | ? |
| double sphereOfInfluence | The radius of the body's sphere of influence, in meters, measured from the center of the planet (not sea level). |
| double staticPressureASL | ? |
| AnimationCurve temperatureCurve | ? |
| PlanetQuadTreeController terrainController | ? |
| bool tidallyLocked | ? |
| array of float timeWarpAltitudeLimits | ? |
| bool useLegacyAtmosphere | If True then atmospheric pressure is determined by atmosphere at sea level decreasing 1/2.718 every scaleHeight kilometers. Lowest possible pressure value is 1e-6 when useLegacyAtmosphere = True. |
| bool use_The_InName | ? |
| Vector3d zUpAngularVelocity | ? |
Methods
The following are methods included in CelestialBody.
| Signature | Description |
|---|---|
| double GetAltitude(Vector3d worldPos) | The altitude above sea level of a given world position, in meters. |
| Bounds getBounds() | Looks like a sphere for detecting potential collisions. Has a radius substantially larger than the body's radius—presumably to account for terrain and atmospheric height plus a safety margin. |
| double GetLatitude(Vector3d worldPos) | The latitude of a given world position, in degrees. |
| double GetLongitude(Vector3d worldPos) | The longitude of a given world position, in degrees. The returned value doesn't seem to stay in any particular range. It may be > 360 or < 0. You'll probably want to do some modulo arithmetic to force this into a certain range like -180 to 180 or 0 to 360. |
| string GetName() | Same as name property.
|
| Vector3 GetObtVelocity() | Infinite loop? (version 0.23.5) |
| Orbit GetOrbit() | Same as orbit.
|
| OrbitDriver GetOrbitDriver() | Same as orbitDriver.
|
| Vector3d GetRelSurfacePosition(Vector3d worldPosition) | Converts a world position into a body-relative position? |
| Vector3d GetRelSurfacePosition(double lat, double lon, double alt) | Returns position in body-relative coordinates for a given longitude/latitude/altitude. Same as GetSurfaceNVector * (body radius + alt). |
| Vector3d getRFrmVel(Vector3d worldPos) | The reference frame of the planet's surface rotates with respect to an inertial reference frame. For example, a ship landed on the planet's surface is actually moving with respect to an inertial frame, because the planet is rotating. This function gives the difference between a velocity in the rotating frame and the same velocity in the inertial frame. You can use it to convert an inertial frame velocity (like the one returned by Orbit.GetVel()) to a rotating frame velocity by (rotating frame velocity) = (inertial frame velocity) - body.GetRFrmVel(position).
|
| Vector3d GetSrfVelocity() | Always returns a zero vector. (as of version 0.23.5) |
| Vector3d GetSurfaceNVector(double lat, double lon) | Returns a unit vector that is normal to the sphere of the planet at the given latitude and longitude. (Tells you which way is "up" at a given point on the planet.) |
| Transform GetTransform() | Same as bodyTransform field
|
| Vector3d GetWorldSurfacePosition(double lat, double lon, double alt) | Returns the world position corresponding to a given latitude, longitude, and altitude above sea level. |
| bool HasChild(CelestialBody body) | True if the given body orbits this one. Doesn't seem to need to be a direct orbit—can be something that orbits something that orbits this. Inverse of HasParent.
|
| bool HasParent(CelestialBody body) | True if the given body orbits is orbited by this one. Doesn't seem to need to be a direct orbit—can be something that's orbited by something that's orbited by this. Inverse of HasChild.
