The Moon and Jupiter will make a close approach, passing within 2°11' of each other.

From London (click to change), the pair will become visible at around 21:35 (BST) as the dusk sky fades, 34° above your southern horizon. They will then sink towards the horizon, setting 5 hours and 40 minutes after the Sun at 02:45.

At the moment of closest approach, the Moon will be at mag -12.2, and Jupiter at mag -2.2, 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 12h53m00s -01°45' Virgo -12.2 30'03"3
Jupiter 12h50m00s -03°49' Virgo -2.2 39"4

The coordinates above are given in J2000.0. The pair will be at an angular separation of 119° from the Sun, which is in Taurus at this time of year.
