The planets Jupiter and Mars will make a close approach, passing within a mere 43.7 arcminutes of each other.
From Cambridge , the pair will become visible at around 20:26 (EDT), 59° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 02:50.
Jupiter will be at mag -2.2; and Mars will be at mag 0.3. Both objects will lie in the constellation Leo.
They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
At around the same time, the pair will also share the same right ascension – called a conjunction.
A graph of the angular separation between Jupiter and Mars around the time of closest approach is available here.
The positions of the pair at the moment of closest approach will be as follows:
Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
Jupiter | 10h12m30s | 12°22'N | Leo | -2.2 | 38"1 |
Mars | 10h13m50s | 13°01'N | Leo | 0.3 | 8"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 105° from the Sun, which is in Aries at this time of year.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
