The Moon and Venus will make a close approach, passing within 2°42' of each other.

From London (click to change), the pair will be visible in the dawn sky. They will rise at 02:13 (BST), 2 hours and 55 minutes before the Sun, and attain an altitude of 20° above the eastern horizon before fading from view as dawn breaks at around 04:40.

At the moment of closest approach, the Moon will be at mag -10.5, and Venus at mag -4.5, both in the constellation Taurus.

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 Venus at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 05h06m00s +18°01' Taurus -10.5 32'57"4
Venus 05h04m30s +20°42' Taurus -4.5 15"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 40° from the Sun, which is in Gemini at this time of year.
