The Moon's monthly orbit around the Earth will carry it to its closest point to the Sun – its perihelion – at a distance of 1.0137 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 1.0163 AU from the Sun, and the Moon will lie at a distance of 1.0137 AU from the Sun.

This distance between the Earth and Moon will be 0.0026 AU (391,000 km).

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

Object Right Ascension Declination Constellation Angular Size
The Moon 05h13m40s +22°07' Taurus 30'31"
Sun (centre) 05h56m +23°26' Taurus 31'28"

The coordinates above are given in J2000.0.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.


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.
