Don’t Miss 2025’s Jaw-Dropping Planetary Conjunction—Jupiter Meets Mercury Tonight in a Rare Dusk Dance
Mercury and Jupiter delight stargazers with a rare close pass just after sunset—learn the best way to see this fleeting display tonight.
- Date: Early June 2025
- Separation: Just 2° apart
- Visibility Window: Only 30 minutes after sunset
- Best Viewing: Find a clear, unobstructed western horizon
Imagine two of the solar system’s brightest wanderers snuggling together in the twilight sky—tonight, that’s exactly what’s happening! Jupiter and Mercury form a rare and striking conjunction, visible for a brief moment after sunset.
This celestial event offers a fleeting but stunning view: Mercury, dazzling at magnitude –1.3, hovers just to the upper right of brilliant Jupiter, shining at –1.9. From the moment the Sun dips below the horizon, you’ll have less than half an hour to catch this planetary duo before they sink out of sight.
Want to maximize your chance of seeing this cosmic pairing? Don’t wait: grab your binoculars and head out to an area with a wide-open view to the west.
NASA and Space.com recommend always waiting until the Sun is fully set before using any optics for safety.
Why Is This Conjunction So Special?
Planetary conjunctions like this are rare, especially with planets as bright and iconic as Jupiter and Mercury. Tonight, these planets appear just two degrees apart—less than a thumb’s width held at arm’s length!
Though Mercury is much smaller, it appears nearly as bright because it’s far closer to Earth. Through binoculars—or a wide-field telescope eyepiece—you’ll spot Mercury’s tiny, crescent-like disc, 89% illuminated, next to Jupiter’s much larger, fully lit globe. Jupiter’s four famous Galilean moons will be present too, but the twilight glare may make them difficult to spot.
When and Where Can You See the Conjunction?
For the best spectacle:
- Head outside as soon as the Sun has fully set (check local sunset times; for 40°N, 90°W it’s around 8:27 P.M.).
- Face west with an open, unobstructed view—hills and trees can block your view of the low-hanging planets.
- Look for two bright “stars” nestled close together just above the horizon.
- Use binoculars for a closer look—but only when the sky is dark enough for safety.

What Will You See?
Mercury sits just to Jupiter’s upper right, both fitting easily into a single binocular view. Mercury appears 5″ wide, while Jupiter looms at 32″, a dramatic size difference. Despite their distance—Mercury about 116 billion miles away, Jupiter almost five times farther—both planets will shine with fierce intensity in the deepening dusk.
Jupiter’s iconic Great Red Spot is also transiting its face this morning for those with telescope access and a clear view—although twilight may make it tricky to catch.

Skywatching Tips: How to Prepare
– Double-check sunset time for your location.
– Find a spot with a clear western horizon—parks or hilltops work well.
– Binoculars are ideal, but a small telescope gives breathtaking detail.
– Be patient; arrive 10–15 minutes early to set up.
– Never point optical devices near the Sun—wait until it’s fully set!
Q&A: Conjunction Curiosities
Q: How often do Jupiter and Mercury pass this close together?
A: Not often! Such close encounters happen roughly every few years—but brightness, visibility, and sky conditions rarely align this perfectly.
Q: Can I see the moons of Jupiter?
A: It’s possible with steady hands and a clear sky, but the twilight glow will make the moons faint.
Q: What’s next on the night sky calendar?
A: June is packed with events—keep an eye out for Saturn rising in the east at dawn and a spectacular full Strawberry Moon later this month.
