Venus, 134340 Pluto and Mars will make a close approach, passing within 2°18' of each other.
From Cambridge , the trio will become visible at around 17:29 (EDT), 37° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 21:12.
Venus will be at mag -4.6; 134340 Pluto will be at mag 0.0; and Mars will be at mag 1.1. The trio will lie in the constellation Pisces.
They will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between Venus and 134340 Pluto around the time of closest approach is available here.
The positions of the trio at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Venus | 23h52m30s | 1°20'N | Pisces | -4.6 | 31"4 |
| 134340 Pluto | 00h00m00s | 0°00'N | Pisces | 0.0 | 0"0 |
| Mars | 00h14m00s | 1°08'N | Pisces | 1.1 | 5"0 |
The coordinates above are given in J2000.0. The trio will be at an angular separation of 45° from the Sun, which is in Capricornus at this time of year.
