Venus and Mars will share the same right ascension, with Venus passing 0°29' to the north of Mars.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Fairfield, the pair will become visible around 20:49 (EDT), 11° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 28 minutes after the Sun at 21:57.

Venus will be at mag -3.9, and Mars at mag 1.8, both in the constellation Leo.

The pair 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.

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

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 09h28m30s +16°38' Leo -3.9 11"6
Mars 09h28m30s +16°08' 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.
