Detailed Description

Author

Bogdan Marinov

This class implements a minor planet (an asteroid).

There are two main reasons for having a separate class from Planet:

• visual magnitude calculation (asteroids use the H,G system; Stellarium's default algorithm is not easily applied to asteroids);
• support for minor planet numbers and provisional designations.

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

Member Function Documentation

renderProvisionalDesignationinHtml()

static QString MinorPlanet::renderProvisionalDesignationinHtml ( QString  plainText )

static

Returns

an empty string if the source string is not a provisional designation.

setAbsoluteMagnitudeAndSlope()

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

These are the parameters in the IAU's two-parameter magnitude system for minor planets. They are used to calculate the apparent magnitude at different phase angles.

Parameters

magnitude	Absolute magnitude H
slope	Slope parameter G. This is usually [0..1], sometimes slightly outside. Allowed here [-1..2].

setMinorPlanetNumber()

void MinorPlanet::setMinorPlanetNumber

(

int

number

)

The number should be specified as an additional parameter, as englishName is passed as a constant to Planet's constructor. The number can be set only once. Any further calls of this function will have no result.

setProvisionalDesignation()

void MinorPlanet::setProvisionalDesignation

(

QString

designation

)

At the moment, the only role is for it to be displayed in the info field.

translateName()

virtual void MinorPlanet::translateName ( const StelTranslator &  trans )

virtual

Function overridden to handle the problem with name conflicts.

Reimplemented from Planet.
