The Moon and Saturn will make a close approach, passing within a mere 21.1 arcminutes of each other. From some parts of the world, the Moon will pass in front of Saturn, creating a lunar occultation. The Moon will be 6 days old.

From South El Monte , the pair will become visible at around 19:49 (PDT), 28° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 17 minutes after the Sun at 22:36.

The Moon will be at mag -11.4; and Saturn will be at mag 0.4. Both objects will lie in the constellation Libra.

They will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 69° from the Sun, which is in Leo at this time of year.

The circumstances of this event were computed using the DE430 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.
