Observe the conjunction of Venus and Jupiter in September 2025

• Venus and Jupiter will be in conjunction on September 12, 2025.
• The Perseid meteor shower will reach its peak on September 12.
• It is better to observe the planets to the east of the sunrise.

In September 2025, an important astronomical event will take place: the conjunction of Venus and Jupiter. These two brightest planets will be so close to each other that they will appear as a "double star." The main conjunction will happen on September 12, when the planets will be less than one degree apart. Observers can see them roughly from 3:00 to 6:00 AM local time.

This week will be particularly favorable for observation, as the planets will gradually come closer to each other. The best time for observation is just before sunrise, looking at the eastern-northern horizon. Venus, with a brightness of -4.0, will be brighter than Jupiter, which has a brightness of -1.9.

Additionally, in September, you can also observe the Perseid meteor shower, which will reach its peak on the night of September 12 to 13. However, the brightness of the moon may reduce the visibility of meteors, which can appear up to 75 times per hour. Observers can still see bright meteors, regardless of this.

After the conjunction, the planet parade will continue, including Mercury, which will be visible in the morning sky. The conjunction of Venus and Jupiter is just one of many astronomical phenomena that can be observed this month.
