Solar Day

Functions
template<typename T >
T	EGXPhys::SolarDay (const T orbitalPeriodIns, const T siderealDayIns)
	Calculates the solar day, \(T_{Solar}\), of a celestial object in seconds from the length of the celestial object's orbital period, \(T_{Orbit}\), and sidereal day, \(T_{Sidereal}\). A solar day is the time it takes for the celestial object to rotate so the body (sun) it is orbiting appears in the same position in the sky overhead. \[ T_{Solar}=\dfrac{T_{Orbit} * T_{Sidereal}}{T_{Orbit} - T_{Sidereal}}\] .

SolarDay()

template<typename T >

T EGXPhys::SolarDay	(	const T	orbitalPeriodIns,
		const T	siderealDayIns
	)

Calculates the solar day, \(T_{Solar}\), of a celestial object in seconds from the length of the celestial object's orbital period, \(T_{Orbit}\), and sidereal day, \(T_{Sidereal}\). A solar day is the time it takes for the celestial object to rotate so the body (sun) it is orbiting appears in the same position in the sky overhead.

\[ T_{Solar}=\dfrac{T_{Orbit} * T_{Sidereal}}{T_{Orbit} - T_{Sidereal}}\]

Parameters

orbitalPeriodIns	\( T_{Orbit}\ (s)\) Orbital period of the celestial object in seconds.
siderealDayIns	\( T_{Sidereal}\ (s)\) Sidereal day of the celestial object in seconds. Negative number indicates the planet has retrograde rotation.

Returns

\( T_{Solar}\ (s)\) Solar day of the celestial object in seconds.
