virtual double Planet::getAngularSize

(

const StelCore *

core

)

const [virtual]

Return the angular radius of a circle containing the object as seen from the observer with the circle center assumed to be at getJ2000EquatorialPos().

Returns:

radius in degree. This value is the apparent angular size of the object, and is independent of the current FOV.

Implements StelObject.

virtual double Planet::getCloseViewFov

(

const StelCore *

)

const [virtual]

Return the best FOV in degree to use for a close view of the object.

Reimplemented from StelObject.

Vec3d Planet::getEclipticPos

(

)

const

Get the Planet position in the parent Planet ecliptic coordinate in AU.

virtual QString Planet::getEnglishName

(

void

)

const [inline, virtual]

Return object's name in english.

Implements StelObject.

virtual Vec3f Planet::getInfoColor

(

void

)

const [virtual]

Get a color used to display info about the object.

Reimplemented from StelObject.

virtual QString Planet::getInfoString	(	const StelCore *	core,
		const InfoStringGroup &	flags
	)			const [virtual]

Get a string with data about the Planet.

Planets support the following InfoStringGroup flags:

• Name
• Magnitude
• RaDec
• AltAzi
• Distance
• Size
• PlainText
• Extra1: Heliocentric Ecliptical Coordinates & Observer-planetocentric Ecliptical Coordinates
• Extra2: Phase, illumination, phase angle & elongation from the Sun

  Parameters:

  	core	the StelCore object
  	flags	a set of InfoStringGroup items to include in the return value.

  Returns:

  a QString containing an HMTL encoded description of the Planet.

Implements StelObject.

Reimplemented in Comet, and MinorPlanet.

virtual Vec3d Planet::getJ2000EquatorialPos

(

const StelCore *

core

)

const [virtual]

Get observer-centered equatorial coordinates at equinox J2000.

Implements StelObject.

virtual QString Planet::getNameI18n

(

void

)

const [inline, virtual]

Return translated object's name.

Implements StelObject.

double Planet::getRadius

(

void

)

const [inline]

Get the radius of the planet in AU.

Returns:

the radius of the planet in astronomical units.

virtual double Planet::getSatellitesFov

(

const StelCore *

)

const [virtual]

Return the best FOV in degree to use for a global view of the object satellite system (if there are satellites).

Reimplemented from StelObject.

virtual float Planet::getSelectPriority

(

const StelCore *

)

const [virtual]

Return a priority value which is used to discriminate objects by priority As for magnitudes, the lower is the higher priority.

Reimplemented from StelObject.

virtual QString Planet::getType

(

void

)

const [inline, virtual]

Return object's type. It should be the name of the class.

Implements StelObject.

virtual float Planet::getVMagnitude	(	const StelCore *	core,
		bool	withExtinction = false
	)			const [virtual]

Return object's apparent V magnitude as seen from observer.

Reimplemented from StelObject.

Reimplemented in Comet, and MinorPlanet.

virtual void Planet::translateName

(

StelTranslator &

trans

)

[virtual]

Translate planet name using the passed translator.

Reimplemented in MinorPlanet.
