Venus and Mars at their Closest for Two Years

November 3rd, 2015

Venus and Mars are now at their closest in the pre-dawn sky with just over a full Moon’s width between them. This is the last of the planetary conjunctions that have been taking place over the past month or so and while it’s definitely worth getting up early for, this is more of a primer for their next close encounter.

On October 4th, 2017, the two worlds will be appear just 12 arc seconds apart in the pre-dawn sky. What does this mean? Well, the full Moon is roughly thirty arc seconds wide. Venus and Mars will be forty-one arc seconds apart today – November 3rd – so in two years time, the planets will be about three times closer together.

But like I said, that’s two years away. Better set that alarm clock.
