Venus and Mars will make a close approach, passing within 0°28' of each other.

From Ashburn, the pair will be difficult to observe as they will appear no higher than 13° above the horizon. They will become visible around 20:54 (EDT) as the dusk sky fades, 13° above your western horizon. They will then sink towards the horizon, setting 1 hour and 36 minutes after the Sun at 22:10.

Venus will be at mag -3.9; and Mars will be at mag 1.8. Both objects will lie in the constellation Leo.

They will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between Venus and Mars around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 09h29m50s +16°31' Leo -3.9 11"7
Mars 09h29m10s +16°05' Leo 1.8 3"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 28° from the Sun, which is in Gemini at this time of year.
