Venus and Jupiter Conjunctions

Venus and Jupiter are the two brightest planets, so when they meet in the same small patch of sky the pairing is unmistakable: two brilliant points you can sometimes cover with a fingertip. Here are the upcoming and most recent meetings, worked out live in your browser.

About this pairing

A conjunction is the moment two planets share the same position along the zodiac, the line the Sun, Moon and planets all trace across our sky. Venus shines at about magnitude minus 4 and Jupiter near minus 2, far brighter than any star, so a Venus-Jupiter conjunction is the easiest of all to spot. The two meet a little more than once a year on average, though the spacing wanders because Venus keeps close company with the Sun.

Some of these meetings are strikingly tight, with the pair drawing within a fraction of a degree, while others pass a few degrees apart. The separation column below shows how close each one runs, in degrees or, for the closest, in arcminutes (sixty to a degree).

Because Venus never strays far from the Sun, a Venus-Jupiter conjunction is always a dawn or dusk event, low in the east before sunrise or the west after sunset. A close one in June of 2 BC, when the two all but merged into a single star in Leo, is one of several events that have been proposed as the Star of Bethlehem, although that remains one hypothesis among many rather than an established fact.

Watching this pair

Plan around the twilight. A Venus-Jupiter meeting never strays into the midnight sky, so the whole show happens within an hour or two of sunrise or sunset, low over an open horizon; scouting a spot with a clear east or west line of sight matters more than any equipment. Binoculars turn the pair into an event: any pass closer than about five degrees fits comfortably in a standard binocular field, two planets in one circle of sky.

The pair also produces the sky's most reliable case of mistaken identity. In the rare passes closer than about a tenth of a degree the two blend, for most eyes, into a single dazzling light, and every close Venus-Jupiter conjunction brings a fresh crop of reports of a strange brilliant object over the sunset. If a friend asks about the impossibly bright star hanging low in the west, the table above probably has the answer.

Photographing Venus and Jupiter

A Venus-Jupiter conjunction is one of the most forgiving targets a camera ever gets. Both planets are bright enough to register in the few minutes after sunset while the sky still holds color, so even a phone braced on a wall or a low tripod catches them cleanly. The trick is composition rather than equipment: set a recognizable foreground low in the frame, a ridgeline, a rooftop, a bare tree, and let the two planets ride the twilight gradient above it.

For a more deliberate shot, keep the exposure short, roughly half a second to two seconds at a moderate ISO, so the planets stay crisp points instead of swelling into blobs, and reach for a modest telephoto around 100 to 200 millimeters to tighten the pair while still holding the color of the sky. The enemy is glare. Shoot while the scene is still blue or gold rather than fully dark, because blazing Venus begins to flare once the background goes black and the quiet balance of the pairing is lost.

The Star of Bethlehem question

No conjunction carries more historical weight than the Venus-Jupiter meetings. In June of 2 BC the two drew so close in the constellation Leo that to most eyes they merged into a single extraordinarily bright star, and that event is one of several proposed explanations for the Star of Bethlehem. It deserves to be stated plainly as a hypothesis rather than a settled fact: the chronology of the nativity is uncertain, rival candidates including the triple Jupiter-Saturn conjunction of 7 BC have their own supporters, and no sky event can be tied to the account with real confidence.

What the history captures is how commanding a close Venus-Jupiter pass looks, the same impression the pairing still makes on anyone who catches it low over the sunset. The pairing returns a little more often than once a year because Venus is always near the Sun, and the Sun laps slow-moving Jupiter about once a year; as Venus swings out to one side of the Sun and back, it sweeps past Jupiter around each of those passages, now and then twice in a single round. Venus itself comes back to nearly the same place in the sky every eight years, the near-repeat that draws the Venus pentagram; only some of its passes by Jupiter are the tight, unforgettable kind.

Frequently asked questions

How often do Venus and Jupiter meet in the sky?

On average a little more than once a year, though the spacing wanders because Venus never strays far from the Sun. The exact upcoming and recent dates are in the table above.

Why is a Venus-Jupiter conjunction so easy to see?

Venus and Jupiter are the two brightest planets, far brighter than any star, so when they pass close together the pairing is unmistakable to the naked eye from almost anywhere with a clear horizon. Because Venus stays near the Sun, the meeting is always low in the dawn or dusk sky.

Can you see Venus and Jupiter in daylight during a conjunction?

Venus, yes: it is bright enough to pick out in a clean blue sky if you know exactly where to look. Jupiter itself is a much harder daylight catch, at the edge of what sharp eyes manage, and a close conjunction is its best chance because blazing Venus marks the spot. Never sweep for either anywhere near the Sun.

Why do close Venus-Jupiter conjunctions get reported as a single bright star?

In the rare passes closer than about a tenth of a degree, the combined glare of the two brightest planets blends into what most eyes read as one dazzling light. Those are the meetings that generate waves of reports about a brilliant new star low in the twilight, and the proposed Star of Bethlehem link to the 2 BC event rests on exactly that effect.

Is the Venus-Jupiter conjunction the Star of Bethlehem?

It is one candidate among several, not a proven answer. The close pass of 2 BC in Leo is often cited, but the date of the nativity is uncertain and other events, including the triple Jupiter-Saturn conjunction of 7 BC, are argued just as strongly. The honest position is that the Star cannot be tied to any single astronomical event with confidence.
