If you’ve stepped outside this evening and wondered what star is next to the Moon tonight, you’re not alone. Skywatchers across the United States are witnessing a beautiful pairing in the January sky — the bright planet Jupiter, shining close to the waxing crescent Moon. Though often mistaken for a star due to its brightness, that glowing “star” beside the Moon tonight is in fact Jupiter, the largest planet in our solar system.

The Moon and Jupiter’s Close Approach Tonight
Tonight, January 4, 2026, offers one of the most striking early-year sky scenes visible from across the continental U.S. As twilight deepens, look toward the southwestern sky after sunset. You’ll see the crescent Moon, about 18% illuminated, positioned close to a brilliant “star-like” object — that’s Jupiter.
The two appear exceptionally close to each other this evening, separated by only a few degrees. For most U.S. locations, their conjunction — the moment they appear nearest in the sky — peaks shortly after 7:00 p.m. local time. Even to the unaided eye, the pair is unmistakable: Jupiter glows with a steady, golden-white light, while the Moon’s soft crescent gleams above it.
This visual pairing is purely a line-of-sight effect. In reality, the Moon is about 238,900 miles (384,000 kilometers) away from Earth, while Jupiter lies roughly 460 million miles distant. Yet their alignment from our perspective creates a dazzling display that even city dwellers can enjoy through light haze or urban glow.
Why Jupiter Shines So Brightly Beside the Moon
Many people mistake Jupiter for a bright star, especially during its peak evening visibility. The planet’s brilliance comes from sunlight reflecting off its thick cloud layers made of ammonia and water ice crystals. Because Jupiter’s atmosphere is extremely reflective, it outshines nearly every star in the night sky — only Venus and occasionally Sirius rival it in brightness.
In early January 2026, Jupiter remains near its opposition season, meaning Earth is positioned directly between the Sun and Jupiter. That alignment makes the planet appear larger and brighter than usual when viewed from our planet. Its steady glow, without the twinkle characteristic of stars, helps distinguish it easily.
How to Find Jupiter and the Moon Tonight
You don’t need a telescope to enjoy this event. Here’s how to spot it:
- When to Look: Step outside about 45 minutes after sunset (between 5:45 and 6:30 p.m. local time).
- Where to Look: Face the southwest. The Moon will be low in the sky, with Jupiter shining just to its right or slightly below it, depending on your region.
- Equipment: Binoculars will enhance the view. Through a small telescope, you may even glimpse Jupiter’s four largest moons — Io, Europa, Ganymede, and Callisto — as tiny dots near the planet.
- Best Viewing Conditions: Find an open area with an unobstructed view of the horizon. Avoid bright lights or buildings that block your southwestern view.
For photographers, the pairing offers a stunning opportunity. Using a tripod and short exposure (around 1/10 second at ISO 200) captures the Moon’s detail and Jupiter’s glow in one frame.
What Makes This Pairing Special
Moon-planet conjunctions occur several times each year, but tonight’s event stands out for its clarity, brightness, and timing. The thin crescent Moon enhances the contrast against Jupiter’s steady light, making the sight particularly eye-catching for casual observers.
Astronomers note that Jupiter’s position in Aries the Ram during early 2026 gives stargazers a prime chance to trace nearby constellations as well. Once the Moon sets later in the evening, you can spot the faint outline of Aries and, further east, the glittering Pleiades star cluster in Taurus.
This event also marks one of the final visible lunar pairings with Jupiter before the planet moves gradually toward the solar glare by spring. So, if skies are clear tonight, this is one to mark on your calendar.
A Brief Look at What’s Coming Next
If tonight’s conjunction leaves you wanting more, the celestial calendar ahead is equally promising:
- January 8–9, 2026: The Moon moves eastward toward the Pleiades and Aldebaran, forming a beautiful alignment in Taurus.
- January 22, 2026: The Moon and Venus pair up in the early morning sky.
- February 2, 2026: The Moon once again visits Jupiter, this time appearing on its opposite side.
Such regular encounters help amateur astronomers track the Moon’s orbital progress through the zodiac constellations, completing a full cycle roughly every 27.3 days.
How Astronomers Predict Lunar-Planet Alignments
These sky events are calculated years in advance using precise orbital data. Both the Moon and Jupiter follow predictable paths known as orbital planes, which allow astronomers to forecast close approaches, eclipses, and occultations (when one body passes in front of another).
Computer models from organizations such as NASA’s Jet Propulsion Laboratory (JPL) and the International Astronomical Union (IAU) provide accurate positional data to the arcsecond. That precision ensures events like tonight’s Moon-Jupiter conjunction can be predicted decades ahead.
For the 2026 alignment, the Moon passes about 3.8 degrees north of Jupiter, visible across all 50 U.S. states. While the two objects won’t overlap or cause an occultation tonight, their separation is close enough to produce a visually dramatic pairing.
Observing Tips for Families and Amateur Astronomers
Lunar conjunctions are perfect introductions to backyard astronomy. They require no special skills or expensive equipment — just curiosity and a clear sky. To make the most of tonight’s viewing:
- Bring Binoculars: A 7×50 or 10×50 pair will reveal Jupiter’s disk and possibly its moons.
- Use a Tripod: Even a smartphone tripod stabilizes your shot for clearer photos.
- Check the Weather: High clouds can blur Jupiter’s light, so aim for crisp, dry evenings.
- Educate Kids: Explain how the Moon moves eastward nightly, overtaking planets along the ecliptic.
- Note the Timing: The Moon sets around 9:00 p.m. in most U.S. regions, so observe before then.
Families can turn this into a fun science moment — sketching what they see and comparing it to astronomy apps like SkySafari or Stellarium Mobile, which show real-time sky maps.
The Science Behind Why the Moon Often Appears Near Planets
Because the Moon orbits Earth within roughly the same plane as the major planets — the ecliptic plane — it frequently passes near them from our perspective. This alignment makes close approaches (conjunctions) a regular part of the lunar cycle.
Each month, the Moon moves about 13 degrees eastward per day, so it meets a new planet or bright star cluster roughly every few nights. Jupiter’s slow motion against the background stars means several lunar conjunctions happen in succession over a few months before the Moon moves on to other regions of the sky.
Common Misconceptions About the “Star” Beside the Moon
Many people believe the object near the Moon must be a star, but several clues help tell the difference:
- Stars twinkle; planets don’t. The steady glow of Jupiter tonight comes from reflected sunlight rather than intrinsic burning like stars.
- Stars remain fixed; planets move. Watch over consecutive nights, and Jupiter’s position will shift relative to nearby stars.
- Color and brightness. Jupiter’s soft golden hue and intense shine make it distinct from even the brightest stars.
If you’re ever unsure, astronomy apps and simple online sky charts can instantly identify celestial neighbors of the Moon on any given night.
Historical and Cultural Connections
Throughout history, bright conjunctions of the Moon and Jupiter have inspired myth and meaning. Ancient Greek astronomers associated Jupiter with Zeus, the king of gods, symbolizing power and protection. In many Native American traditions, such pairings marked seasonal transitions, signaling important times for planting or storytelling.
Today, the same awe persists — but with added scientific understanding. We can now appreciate both the visual beauty and the cosmic mechanics behind the show, blending ancient wonder with modern knowledge.
Final Thoughts: Don’t Miss the Moon and Jupiter Tonight
Tonight’s sky offers a brilliant start to 2026 for U.S. stargazers. The slender crescent Moon and shining Jupiter create one of the most photogenic and easily visible pairings of the winter season. Whether viewed from a quiet backyard or a city balcony, the scene reminds us how accessible and rewarding skywatching can be.
So step outside after sunset, face southwest, and take a moment to look up — the same glowing partnership visible to ancient astronomers is shining again above us tonight.
