Jupiter and Mars will make a close approach, passing within 0°12' of each other.
Jupiter will be at mag -1.9; and Mars will be at mag 1.4. Both objects will lie in the constellation Libra.
They will be close enough to fit within the field of view of a telescope, but will also be visible to the naked eye or through a pair of binoculars.
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|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 58° from the Sun, which is in Sagittarius at this time of year.
