Venus, Jupiter, and Gemini
Brilliant Venus continues to dominate the eastern sky before sunrise. On August 1st, the Morning Star moves in front of Gemini’s rich star fields as it steps eastward. It is about 20° up in the eastern sky an hour before sunrise, around mid-twilight. Bright Jupiter is 10.4° to Venus’ lower left.
During August, Venus moves through Gemini’s star fields against the distant backdrop of the Milky Way before stepping into Cancer on the 24th. It passes the star cluster Messier 35 on the 2nd, a pretty scene through a binocular. Watch its eastward motion as it heads toward a conjunction with Jupiter on August 12. On the 20th, look for a rare celestial gathering: Venus, the crescent moon, and Pollux fit in a circle 7.2° in diameter, a rare close gathering.
Venus Reaches Earliest Rising Interval
At the beginning of August, Venus rises nearly three hours before sunrise. It is at its maximum rising interval before sunrise. Slowly, Venus rises later compared to sunrise, losing 16 minutes of rising time at month’s end.
On August 2nd, the Morning Star closes to within 10° of Jupiter, approximately the distance across your fist, from pinky knuckle to thumb knuckle, at arm’s length, through the August 12th conjunction and until August 22nd.
Venus-Jupiter Conjunction
Each morning watch Venus pass Gemini’s bright stars. A binocular assists with the view. It passes Jupiter with a gap of 0.9° on the morning of the 12th. While not a Proximate conjunction, one closer than 0.5°, the two brightest planets also ranking as the third and fourth brightest celestial bodies, stand together in the eastern sky before sunrise against a rich starry background.
Do not miss this event. At next spring’s Venus-Jupiter conjunction on June 6, 2026, the pair is 1.6° apart though they appear near Gemini’s Pollux.
Capture the conjunction with a tripod-mounted camera and exposures of several seconds. A steady handheld smartphone camera can record the scene.
In August 2027, they are 0.5° apart, but this occurs at sunset, when the pair is less than 2° above the western horizon.
Sirius Joins Venus and Jupiter in Eastern Sky
During mid-August, Sirius makes its first morning appearance or heliacal rising at the mid-northern latitudes. Look for Venus, Jupiter, and Sirius in the eastern sky during morning twilight. While not close together next month, Venus and Sirius are at nearly the same altitude – height above the horizon – for a few mornings.
Six-Planet Display
Around this time Mercury enters the morning sky joining, Venus, Jupiter, Uranus, Neptune and Saturn, six of the seven bright planets. While not visible simultaneously, Uranus and Neptune are visible before twilight begins and Mercury rises into bright morning light.
On the 18th, Venus passes 10.7° to the lower right of Castor one of the Twins.
Rare Gathering: Venus-Moon-Pollux
Two mornings later, nearly 20° up in the east, Venus passes 7.2° to the lower right of Pollux. The crescent moon, 9% illuminated, is between the Morning Star and Pollux, 4.4° to Venus’ upper left.
Binocular View
Look for the star Kappa Geminorum, 3.6° to the upper left of Venus through a binocular. Venus, Moon, and Pollux fit into a 7.2° circle, a rare close gathering of these bodies and a tight fit into the same binocular field. Bright Jupiter is 8.1° to the upper right of Venus and Mercury is 15.4° to the lower left. All of these celestial bodies fit into a circle 10.2° in diameter. Venus, Moon, and Pollux do not gather this closely again until May 26, 2039.
On the 24th, Venus crosses the Cancer border and begins to approach the Beehive star cluster. From the 27th through September 6th, the planet and the star cluster fit into the same binocular field.
During August, watch Venus overtake and pass Jupiter against Gemini’s star fields. Be sure to observe the rare Venus, Moon, Pollux gathering on the 20th. At month’s end watch Venus approach the Beehive star cluster through a binocular.
