planetMeanAnomaly :: PlanetDetails -> JulianDate -> DecimalDegrees

Calculate the planet mean anomaly.

planetTrueAnomaly1 :: PlanetDetails -> JulianDate -> DecimalDegrees

Calculate the planet true anomaly using approximate method

planetHeliocentricRadiusVector :: PlanetDetails -> DecimalDegrees -> AstronomicalUnits

Calculate Heliocentric Radius Vector. It takes Planet Details and true anomaly.

planetHeliocentricLongitude :: PlanetDetails -> DecimalDegrees -> DecimalDegrees

Calculate Heliocentric Longitude. It takes Planet Details and true anomaly.

planetHeliocentricLatitude :: PlanetDetails -> DecimalDegrees -> DecimalDegrees

Calculate Heliocentric Latitude. It takes Planet Details and heliocentric longitude.

planetProjectedRadiusVector :: PlanetDetails -> DecimalDegrees -> AstronomicalUnits -> AstronomicalUnits

Calculate Heliocentric Radius Vector projected to the ecliptic. It takes Planet Details, planetHeliocentric latitude and Radius Vector

planetProjectedLongitude :: PlanetDetails -> DecimalDegrees -> DecimalDegrees

Calculate Heliocentric Longitude projected to the ecliptic. It takes Planet Details and Heliocentric Longitude

planetEclipticLongitude :: PlanetDetails -> DecimalDegrees -> AstronomicalUnits -> DecimalDegrees -> AstronomicalUnits -> DecimalDegrees

Calculate Ecliptic Longitude. It takes planet projected longitude, planet projected radius vector the Earth's longitude and radius vector.

planetEclipticLatitude :: DecimalDegrees -> DecimalDegrees -> AstronomicalUnits -> DecimalDegrees -> AstronomicalUnits -> DecimalDegrees -> DecimalDegrees

Calculate ecliptic Latitude. It takes the planet's: heliocentric latitude, projected heliocentric longutide, projected heliocentric longitude; the Earth's: heliocentric longitede and heliocentric radius vector. Also it takes the planet's ecliptic longitude.

planetPosition :: (PlanetDetails -> JulianDate -> DecimalDegrees) -> PlanetDetails -> PlanetDetails -> JulianDate -> EquatorialCoordinates1

Calculate the planet's postion at the given date. It takes a function to calculate true anomaly, planet details of the planet, planet details of the Earth and JulianDate.

planetPosition1 :: PlanetDetails -> PlanetDetails -> JulianDate -> EquatorialCoordinates1

Calculate the planet's postion at the given date using the approximate algoruthm. It takes a function to calculate true anomaly, planet details of the planet, planet details of the Earth and JulianDate.

planetDistance1 :: PlanetDetails -> PlanetDetails -> JulianDate -> AstronomicalUnits

Calculates the distance betweeth the planet and the Earth at the given date. It takes the planet's detail, the Earth's details and the julian date.

planetAngularDiameter :: PlanetDetails -> AstronomicalUnits -> DecimalDegrees

Calculates the planet's angular diameter for the given distance.

planetPhase1 :: PlanetDetails -> PlanetDetails -> JulianDate -> Double

Calculate the planet's phase at the given phase. Phase is a fraction of the visible disc that is illuminated. It takes the planet's details, the Earth's details and the julian date. Returns fraction values from 0 to 1.

planetPertubations :: Planet -> JulianDate -> DecimalDegrees

Calculates pertubations for the planet at the given julian date. Returns a value that should be added to the mean longitude (planet heliocentric longitude).

planetBrightLimbPositionAngle :: EquatorialCoordinates1 -> EquatorialCoordinates1 -> DecimalDegrees

Calculate the planet's position-angle of the bright limb. It takes the planet's coordinates and the Sun's coordinates. Position-angle is the angle of the midpoint of the illuminated limb measured eastwards from the north point of the disk.
