Some of the code in this class is re-used from the parent Planet class.

Member Function Documentation

◆ getInfoMap()

virtual QVariantMap Comet::getInfoMap ( const StelCore core) const
virtual

Reimplemented from Planet.

◆ getVMagnitude()

virtual float Comet::getVMagnitude ( const StelCore core) const
virtual

Reimplemented from Planet.

◆ setAbsoluteMagnitudeAndSlope()

void Comet::setAbsoluteMagnitudeAndSlope ( const float  magnitude,
const float  slope 
)

These are the parameters in the IAU's two-parameter magnitude system for comets. They are used to calculate the apparent magnitude at different distances from the Sun. They are not used in the same way as the same parameters in MinorPlanet.

◆ translateName()

virtual void Comet::translateName ( const StelTranslator trans)
virtual

Function overriden to handle the problem with name conflicts.

Reimplemented from Planet.
