Venus and Mars will make a close approach, passing within 0°40' of each other.

From London (click to change), the pair will be visible in the dawn sky. They will rise at 02:29 (GMT), 4 hours and 27 minutes before the Sun, and attain an altitude of 33° above the south-eastern horizon before fading from view as dawn breaks at around 06:33.

At the moment of closest approach, Venus will be at mag -5.0, and Mars at mag 1.4, both in the constellation Virgo.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or a through pair of binoculars.

The precise positions of Venus and Mars at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 11h39m30s +03°00' Virgo -5.0 22"1
Mars 11h40m00s +03°39' Virgo 1.4 4"2

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