The Moon's monthly orbit around the Earth will carry it to its furthest point from the Sun – its aphelion – at a distance of 0.9888 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 aphelion, the Earth will lie at a distance of 0.9862 AU from the Sun, and the Moon will lie at a distance of 0.9888 AU from the Sun.

This distance between the Earth and Moon will be 0.0027 AU (403,000 km).

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

Object Right Ascension Declination Constellation Angular Size
The Moon 10h36m00s 13°33'N Leo 29'35"
Sun (centre) 21h21m 15°26'S Capricornus 32'26"

The coordinates above are given in J2000.0.
