The Moon and Jupiter will make a close approach, passing within 1°20' of each other.

From London (click to change), the pair will be visible in the morning sky. They will become accessible at around 21:33, when they rise 7° above your eastern horizon. They will then reach its highest point in the sky at 03:07, 42° above your southern horizon. They will be lost to dawn twilight at around 07:20, 19° above your western horizon.

At the moment of closest approach, the Moon will be at mag -12.4, and Jupiter at mag -2.4, both in the constellation Leo.

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 11h32m30s +02°59' Leo -12.4 29'45"4
Jupiter 11h34m10s +04°16' Leo -2.4 41"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 134° from the Sun, which is in Capricornus at this time of year.
