The Moon and Jupiter will make a close approach, passing within 4°58' of each other. The Moon will be 6 days old.

From Washington, the pair will become visible around 21:00 (MDT) as the dusk sky fades, 53° above your south-western horizon. They will then sink towards the horizon, setting at 01:42.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -11.4, and Jupiter at mag -2.0, both in the constellation Cancer.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

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

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

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

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 09h07m30s +12°14' Cancer -11.4 29'53"4
Jupiter 09h12m20s +17°04' Cancer -2.0 34"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 73° from the Sun, which is in Taurus at this time of year.

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.
