This week, planetary positions help chart the moon’s changing phases with Venus marking key points.
This week offers a unique opportunity to observe the movement of the moon through the phases, with the help of Jupiter, Saturn, and Venus. The two giant planets—Jupiter and Saturn—will serve as guides in the evening sky, showcasing the moon’s changing phases. Adding Venus to the mix gives us even more celestial reference points to track the moon’s progress.
On December 6th, observers in London can spot Jupiter and Saturn in the south-western sky around 16:30 GMT. While these planets will be easy to spot, the moon will be more elusive. At only 8% illuminated, you’ll need a clear horizon to catch a glimpse.
By the next evening, the view improves significantly. The moon will be positioned between Venus and Saturn, with 16% illumination. On December 7th, it will move closer to Jupiter, between Jupiter and Saturn, reaching 25% illumination. The following night, the moon will be near Jupiter with 35% illumination. Venus will appear as the brightest and lowest of the planets, while Jupiter will shine brightly from a higher position. Saturn, though fainter, will be nestled between the two brighter planets. For those in the southern hemisphere, these celestial groupings will be visible much higher in the western sky.
