Venus and Jupiter form a 'double star' in the evening sky

Astronomy enthusiasts have a celestial treat in store as Venus and Jupiter converge for a close encounter in the evening sky. This rare alignment, described as a "double star," will be visible between June 7 and June 11, offering a spectacular view for observers.

The planets will be most closely aligned on the evening of June 9, presenting the most striking view of their apparent proximity. According to the Vienna Working Group for Astronomy (WAA), the best viewing times will be between 9:30 PM and 10:30 PM local time, looking towards the west-northwest.

Alexander Pikhard, head of the WAA, cautioned that the apparent closeness in the sky is deceptive. Venus, the brighter of the two planets, will be approximately 180 million kilometers from Earth on June 9. Jupiter, though appearing slightly dimmer, is significantly larger than Venus and much farther away, situated at roughly 905 million kilometers from Earth.

This difference in distance explains why Venus, moving faster through the constellation Gemini, will appear to "overtake" Jupiter. As a result, the angle and distance between the two planets will change nightly. Jupiter will disappear from the evening sky by the end of June, while Venus will remain visible until September 25.

Encounters between Venus and Jupiter are not uncommon, occurring every 11 to 15 months. However, not all of these conjunctions are easily observable. Future opportunities to witness such a planetary rendezvous include early November 2028 in the pre-dawn sky and early September 2029 in the evening twilight.

The apparent closeness in the sky must not be deceiving.
