Detailed Description
A subclass of KSPlanetBase that implements asteroids.
All elements are in the heliocentric ecliptic J2000 reference frame.
Check here for full description: https://ssd.jpl.nasa.gov/?sb_elem#legend
The orbital elements are stored as private member variables, and it provides methods to compute the ecliptic coordinates for any time from the orbital elements.
The orbital elements are:
- JD Epoch of element values
- a semi-major axis length (AU)
- e eccentricity of orbit
- i inclination angle (with respect to J2000.0 ecliptic plane)
- w argument of perihelion (w.r.t. J2000.0 ecliptic plane)
- N longitude of ascending node (J2000.0 ecliptic)
- M mean anomaly at epoch JD
- H absolute magnitude
- G slope parameter
- Version
- 1.0

Destructor (empty)
Member Function Documentation
◆ clone()
|
overridevirtual |
Create copy of object.
This method is virtual copy constructor. It allows for safe copying of objects. In other words, KSPlanet object stored in SkyObject pointer will be copied as KSPlanet.
Each subclass of SkyObject MUST implement clone method. There is no checking to ensure this, though.
- Returns
- pointer to newly allocated object. Caller takes full responsibility for deallocating it.
Reimplemented from SkyObject.
Reimplemented in KSPluto.
Definition at line 32 of file ksasteroid.cpp.
◆ findGeocentricPosition()
|
overrideprotectedvirtual |
Calculate the geocentric RA, Dec coordinates of the Asteroid.
- Note
- reimplemented from KSPlanetBase
- Parameters
-
num time-dependent values for the desired date Earth planet Earth (needed to calculate geocentric coords)
- Returns
- true if position was successfully calculated.
Implements KSPlanetBase.
Reimplemented in KSPluto.
Definition at line 39 of file ksasteroid.cpp.
◆ getAbsoluteMagnitude()
|
inline |
This lets other classes like KSPlanetBase access H and G values Used by KSPlanetBase::FindMagnitude.
Definition at line 77 of file ksasteroid.h.
◆ getAlbedo()
|
inline |
- Returns
- the asteroid's albedo
Definition at line 138 of file ksasteroid.h.
◆ getDiameter()
|
inline |
- Returns
- the asteroid's diameter
Definition at line 148 of file ksasteroid.h.
◆ getDimensions()
|
inline |
- Returns
- the asteroid's dimensions
Definition at line 158 of file ksasteroid.h.
◆ getEarthMOID()
|
inline |
- Returns
- the asteroid's earth minimum orbit intersection distance in AU
Definition at line 98 of file ksasteroid.h.
◆ getOrbitClass()
|
inline |
- Returns
- the asteroid's orbit class
Definition at line 118 of file ksasteroid.h.
◆ getOrbitID()
|
inline |
- Returns
- the asteroid's orbit solution ID
Definition at line 108 of file ksasteroid.h.
◆ getPerihelion()
|
inline |
- Returns
- Perihelion distance
Definition at line 88 of file ksasteroid.h.
◆ getPeriod()
|
inline |
- Returns
- the asteroid's period
Definition at line 178 of file ksasteroid.h.
◆ getRotationPeriod()
|
inline |
- Returns
- the asteroid's rotation period
Definition at line 168 of file ksasteroid.h.
◆ getSlopeParameter()
|
inline |
Definition at line 78 of file ksasteroid.h.
◆ getUID()
|
overridevirtual |
Return UID for object.
This method should be reimplemented in all concrete subclasses. Implementation for SkyObject just returns invalidUID. It's required SkyObject is not an abstract class.
Reimplemented from SkyObject.
Definition at line 274 of file ksasteroid.cpp.
◆ isNEO()
|
inline |
- Returns
- true if the asteroid is a near earth object
Definition at line 128 of file ksasteroid.h.
◆ loadData()
|
overridevirtual |
This is inherited from KSPlanetBase.
We don't use it in this class, so it is empty.
