Venus and Jupiter will make a close approach, passing within 1°01' of each other.

From London (click to change), the pair will be visible in the dawn sky. They will rise at 02:17 (GMT), 4 hours and 27 minutes before the Sun, and attain an altitude of 34° above the south-eastern horizon before fading from view as dawn breaks at around 06:21.

At the moment of closest approach, Venus will be at mag -5.1, and Jupiter at mag -1.8, 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 Venus and Jupiter at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 11h06m50s +05°39' Leo -5.1 24"1
Jupiter 11h07m50s +06°38' Leo -1.8 31"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 46° from the Sun, which is in Virgo at this time of year.
