The Moon and Mars will make a close approach, passing within 3°00' of each other.
From London (click to change), the pair will be visible in the dawn sky. They will rise at 03:37 (BST), 3 hours and 40 minutes before the Sun, and attain an altitude of 25° above the south-eastern horizon before fading from view as dawn breaks at around 06:52.
At the moment of closest approach, the Moon will be at mag -10.2, and Mars at mag 1.5, 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 Mars at the moment of closest approach will be as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 38° from the Sun, which is in Libra at this time of year.
