Conjunction of Mercury and Ceres

From the Conjunctions feed


Mercury and 1 Ceres will share the same right ascension, with Mercury passing 3°36' to the south of 1 Ceres.

From South El Monte however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 19° from it.

Mercury will be at mag -0.3, and 1 Ceres at mag 8.9, both in the constellation Scorpius.

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 Mercury 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
Mercury 16h12m10s 23°29'S Scorpius -0.3 5"5
1 Ceres 16h12m10s 19°52'S Scorpius 8.9 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 19° from the Sun, which is in Libra at this time of year.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
