EarthMoonBarycenter Class

The barycenter of the Earth-Moon system. Used when the Earth-Moon system is modeled as a single third body in interplanetary trajectories.

Syntax
public class EarthMoonBarycenter : PlanetarySystemBarycenter, 
	IProvideNaifIdCode

The EarthMoonBarycenter type exposes the following members.

Constructors
  NameDescription
Public methodEarthMoonBarycenter
Initializes a new instance. By default, this uses the same InertialFrame as EarthCentralBody. The CenterOfMassPoint is defined by EarthMoonBarycenter.
Protected methodEarthMoonBarycenter(EarthMoonBarycenter, CopyContext)
Initializes a new instance as a copy of an existing instance.

Properties
  NameDescription
Public propertyCenterOfMassPoint
Gets or sets a point describing the center of mass of this planetary system.
(Inherited from PlanetarySystemBarycenter.)
Public propertyInertialFrame
Gets or sets the default inertial frame for this planetary system.
(Inherited from PlanetarySystemBarycenter.)
Public propertyIsFrozen
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.)
Public propertyIsThreadSafe
Gets a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously.
(Overrides PlanetarySystemBarycenterIsThreadSafe.)
Public propertyNaifIdCode

Gets the NAIF identification code of this central body, barycenter, spacecraft, ground station, or other physical object or location.

A directory of NAIF IDs associated with commonly used Solar System bodies is available at the NAIF website.

Public propertyName
Gets or sets the name of this planetary system's barycenter.
(Inherited from PlanetarySystemBarycenter.)

Methods
  NameDescription
Protected methodCheckForSameDefinition(DefinitionalObject)
Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from PlanetarySystemBarycenter.)
Protected methodCheckForSameDefinition(EarthMoonBarycenter)
Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
Protected methodCheckForSameDefinition(PlanetarySystemBarycenter)
Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides PlanetarySystemBarycenterCheckForSameDefinition(PlanetarySystemBarycenter).)
Public methodClone
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).)
Protected methodComputeCurrentDefinitionHashCode
Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the CheckForSameDefinition(DefinitionalObject) method.
(Overrides PlanetarySystemBarycenterComputeCurrentDefinitionHashCode.)
Public methodStatic memberComputeEarthMoonBarycenterPoint
Computes the position of the Earth-Moon barycenter using the Earth-Moon mass ratio and the positions of the Earth and Moon.
Public methodEnumerateDependencies
Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class.
(Inherited from PlanetarySystemBarycenter.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObject.)
Protected methodFreezeAggregatedObjects
Called by Freeze to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties.
(Inherited from DefinitionalObject.)
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodSynchronizeOrigins
Sets the Origin of the InertialFrame to the CenterOfMassPoint.
(Inherited from PlanetarySystemBarycenter.)
Protected methodThrowIfFrozen
Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodUpdateEarthMoonBarycenterPoint
Updates the CenterOfMassPoint of this EarthMoonBarycenter instance using the Earth-Moon mass ratio and the positions of the Earth and Moon. Then, calls SynchronizeOrigins to update the InertialFrame to use that new point as its origin.
