Conjunction of Uranus and Ceres

From the Conjunctions feed


Uranus and 1 Ceres will share the same right ascension, with Uranus passing 4°02' to the south of 1 Ceres.

From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 4° above the horizon at dusk.

Uranus will be at mag 5.6, and 1 Ceres at mag 8.9, both in the constellation Libra.

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

A graph of the angular separation between Uranus 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:

Object Right Ascension Declination Constellation Magnitude Angular Size
Uranus 14h33m20s 14°39'S Libra 5.6 3"6
1 Ceres 14h33m20s 10°36'S Libra 8.9 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 27° from the Sun, which is in Virgo at this time of year.
