Mars and NGC6530 will make a close approach, passing within 0°11' of each other.

From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 11° above the horizon at dusk.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Mars will be at mag 1.2, and NGC6530 at mag 4.6, both in the constellation Sagittarius.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

A graph of the angular separation between Mars and NGC6530 around the time of closest approach is available here.

The positions of the two objects at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Mars 18h04m30s -24°33' Sagittarius 1.2 4"4
NGC6530 18h04m30s -24°21' Sagittarius 4.6 15'00"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 34° from the Sun, which is in Libra at this time of year.
