The moon is rapidly approaching fullness, and this week it will make a passing encounter with Jupiter on 21 and 22 December.
The chart shows the view looking due south from London at 9pm GMT on 22 December. The moon will be waxing gibbous (getting bigger) with 82% of its visible surface illuminated. Jupiter will be a bright object, shining at around a magnitude of –2.7 in the constellation of Aries, the ram. The pair will also be visible from the southern hemisphere, where they can be easily seen in the northern sky.
