The Moon's monthly orbit around the Earth will carry it to its furthest point from the Sun – its aphelion – at a distance of 1.0179 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 1.0153 AU from the Sun, and the Moon will lie at a distance of 1.0180 AU from the Sun.

This distance between the Earth and Moon will be 0.0027 AU (405,000 km).

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

Object Right Ascension Declination Constellation Angular Size
The Moon 18h08m10s -19°19' Sagittarius 29'27"
Sun (centre) 05h15m +23°02' Taurus 31'30"

The coordinates above are given in J2000.0.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
