NAME

Astro::Montenbruck::Ephemeris::Planet::Moon - Moon.

SYNOPSIS

use Astro::Montenbruck::Ephemeris::Planet::Moon;
my $planet = Astro::Montenbruck::Ephemeris::Planet::Moon->new();
my @geo = $planet->moonpos($t); # apparent geocentric ecliptical coordinates

DESCRIPTION

Child class of Astro::Montenbruck::Ephemeris::Planet, responsible for calculating Moon position for the mean equinox of date.

Formulae are based on analytical theory of by E.E.Brown (Improved Lunar Ephemeris) with accuracy of approx. 1 arc-second.

METHODS

Astro::Montenbruck::Ephemeris::Planet::Moon->new

Constructor.

$self->moonpos($t)

Geocentric ecliptic coordinates of the Moon. The coordinates are referred to the mean equinox od date

Arguments

$t — time in Julian centuries since J2000: (JD-2451545.0)/36525.0

Returns

Hash of geocentric ecliptical coordinates.

• x — geocentric longitude, arc-degrees

• y — geocentric latitude, arc-degrees

• z — distance from Earth, AU
