The Moon's monthly orbit around the Earth will carry it to its furthest point from the Sun – its aphelion – at a distance of 1.0154 AU from the Sun.

This happens at around the time when the Moon's orbit carries it around the far side of the Earth as seen from the Sun, at around the same time that it passes full moon.

At the moment of the Moon's perihelion, the Earth will lie at a distance of 1.0131 AU from the Sun, and the Moon will lie at a distance of 1.0155 AU from the Sun.

This distance between the Earth and Moon will be 0.0024 AU (364,000 km).

The exact positions of the Sun and Moon in the sky will be:

Object Right Ascension Declination Constellation Angular Size
The Moon 17h41m10s 20°35'S Ophiuchus 32'46"
Sun (centre) 04h13m +21°10' Taurus 31'34"

The coordinates above are given in J2000.0.
