The Moon and Jupiter will make a close approach, passing within 2°03' of each other.

From London (click to change), the pair will be visible between 20:10 and 05:33. They will become accessible at around 20:10, when they rise 7° above your eastern horizon, and then reach its highest point in the sky at 00:54, 33° above your southern horizon. They will become inaccessible at around 05:33 when they sink to 7° above your western horizon.

At the moment of closest approach, the Moon will be at mag -12.6, and Jupiter at mag -2.5, both in the constellation Virgo.

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.

The precise positions of the Moon and Jupiter at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 13h10m00s -03°30' Virgo -12.6 30'01"2
Jupiter 13h07m20s -05°27' Virgo -2.5 43"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 174° from the Sun, which is in Pisces at this time of year.
