Detailed Description

A subclass of KSPlanetBase that implements comets.

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.

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:

JD Epoch of element values
q perihelion distance (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)
Tp time of perihelion passage (YYYYMMDD.DDD)
M1 comet total magnitude parameter
M2 comet nuclear magnitude parameter
K1 total magnitude slope parameter
K2 nuclear magnitude slope parameter

Member Function Documentation

◆ clone()

KSComet * KSComet::clone ( ) const

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.

Definition at line 132 of file kscomet.cpp.

◆ findGeocentricPosition()

bool KSComet::findGeocentricPosition	(	const KSNumbers *	num,
		const KSPlanetBase *	Earth = nullptr )

overrideprotectedvirtual

Calculate the geocentric RA, Dec coordinates of the Comet.

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.
