The Moon's monthly orbit around the Earth will carry it to its closest point to the Sun – its perihelion – at a distance of 0.9843 AU from the Sun.

This happens at around the time when the Moon's orbit carries it between the Sun and the Earth, at around the same time that it passes new moon.

At the moment of the Moon's perihelion, the Earth will lie at a distance of 0.9866 AU from the Sun, and the Moon will lie at a distance of 0.9841 AU from the Sun.

This distance between the Earth and Moon will be 0.0025 AU (380,000 km).

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

Object Right Ascension Declination Constellation Angular Size
The Moon 17h50m30s -22°27' Sagittarius 31'22"
Sun (centre) 16h14m -21°13' Scorpius 32'25"

The coordinates above are given in J2000.0.
