Key Takeaways
- Venus is transitioning from the evening sky to the morning sky, with its last prominent appearances occurring in September.
- Significant dates include September 18, when Venus reaches maximum brightness, before eventually fading from view.
- In October, Venus will return as the “Morning Star,” rising significantly before dawn and becoming prominent in the early morning sky.
Venus Bids Farewell as the Evening Star
Since late March, Venus has captivated skywatchers as the “Evening Star,” shining brilliantly shortly after sunset. During this time, it even participated in a stunning three-planet alignment in June, surpassing both Jupiter and Mercury in brightness. However, as the month progresses, Venus is slowly dipping lower in the sky, preparing to replace its evening role with a morning appearance by late October.
Venus has a predictable orbit around the sun, completing 13 revolutions in 8 Earth years. This regular pattern has been observed for centuries, influencing ancient civilizations such as the Aztecs and Mayans. Each year has its distinct characteristics, with the patterns on track to closely resemble those observed in 2018 by 2026.
In September, Venus will shine at its peak, but catching a glimpse may be challenging as the planet gradually descends in the southwestern sky after sunset. Below are key dates for optimal viewing:
- September 7: Venus sets approximately 1¼ hours after sunset.
- September 14: A waxing crescent moon will appear near Venus, offering a picturesque view about 5½ degrees to the left.
- September 18: The planet achieves its greatest brightness at a dazzling magnitude of -4.8, but will be positioned low on the horizon.
- Late September: By month’s end, Venus will set only 35 minutes post-sunset, making it harder to spot.
Typically, the period between Venus reaching its greatest elongation and maximum brilliance would be ideal for skywatching. However, this year has not provided such favorable conditions. Since its peak in June, viewers have found the planet lingering low in the twilight glow rather than rising to a commanding position. By August 15, during its greatest elongation, Venus was already visible only briefly after evening twilight.
For those situated at mid-northern latitudes, Venus’ finale will be notably lower on the horizon. At around 40 degrees north latitude, it will appear just 5½ degrees above the southwest horizon by late September—barely more than half the width of a clenched fist held at arm’s length.
Through a telescope, Venus currently displays a stunning crescent shape. As its sunlit side turns further away from Earth, this crescent becomes thinner and longer, presenting an exquisite arc of light. Observers with steady binoculars may still glimpse this shape in the coming weeks, although the low altitude may cause shimmering views.
By early October, Venus will retreat from the evening sky entirely, reaching inferior conjunction on October 24, which will make it challenging to spot near sunset. However, Venus will emerge once again in the morning sky by November, shining brightly as it becomes the “Morning Star.” This brilliant reappearance is set to coincide with the winter holidays, where it will rise over two hours before dawn, bringing a stunning addition to the pre-dawn sky.
