Mars and 1 Ceres will share the same right ascension, with Mars passing 7°56' to the north of 1 Ceres.
From Ashburn, the pair will be visible in the dawn sky, rising at 02:26 (EDT) – 3 hours and 22 minutes before the Sun – and reaching an altitude of 25° above the south-eastern horizon before fading from view as dawn breaks around 05:15.
Mars will be at mag -0.0, and 1 Ceres at mag 9.0, both in the constellation Aquarius.
A graph of the angular separation between Mars and 1 Ceres around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
