New Moon
Tuesday 3rd Dec 201300:24
The Moon will make a close approach to the Sun in the sky as it sweeps along its eastward path across the night sky. As it does so, it will draw too close to the Sun for observation, passing within a mere 02°52′ of it in the constellation Ophiuchus.
As a result of the Earth, Moon and Sun all lying in a straight line in the Solar System, with the Moon in the middle, we will also see almost exactly the opposite side of the Moon to that which is illuminated by the Sun, meaning that it will appear almost completely unilluminated.
