Mars and 134340 Pluto will share the same right ascension, with Mars passing 1°25' to the south of 134340 Pluto.
From Ashburn, the pair will be visible in the dawn sky, rising at 01:38 (EDT) – 4 hours and 42 minutes before the Sun – and reaching an altitude of 28° above the southern horizon before fading from view as dawn breaks at around 05:54.
Mars will be at mag -0.3, and 134340 Pluto at mag 14.7, both in the constellation Sagittarius.
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 Mars and 134340 Pluto 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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 104° from the Sun, which is in Aries at this time of year.
