Moon Sweeps Past Mars, Jupiter and Regulus as Mercury Hits Inferior Conjunction

Q: When will Jupiter, Mars, and Regulus appear closest before dawn this week, and can you spot the trio without binoculars?

Jupiter, Mars and Regulus will appear closest before dawn on the early mornings of Monday and Tuesday, with the view best just before sunrise in a dark sky. Wednesday is also notable, but mainly because the moon makes its closest appearance to the grouping then. Yes, the trio can be seen without binoculars. Jupiter is extremely bright, Mars is distinctly reddish, and Regulus, the brightest star in Leo, is also visible to the naked eye. Reports tied to this week’s event note that all three are easy to spot from late night into dawn as they rise in the east and climb high before sunrise. Binoculars are optional rather than necessary. They can make the grouping look tighter and help in brighter suburban skies, but the lineup itself is designed for naked-eye viewing, especially from a clear, dark location with an unobstructed eastern horizon. For the best chance of seeing it, look up in the hour before dawn on Monday or Tuesday. Jupiter will stand out as the brightest object, Mars will show a warmer orange-red tint, and Regulus will appear blue-white nearby.

Q: Is this pre-dawn lineup a rare celestial event or part of a bigger pattern unfolding in Leo over the coming weeks?

It is not just a one-off spectacle. This week’s pre-dawn lineup is part of a broader pattern unfolding in Leo as Jupiter, Mars and Regulus draw together along the ecliptic over several weeks. What makes the current view notable is timing and visibility: Jupiter, the brightest object in the group, is already close to Regulus, while Mars is moving steadily toward both. That creates a compact, easy-to-see arrangement before dawn now, with especially good views on Monday and Tuesday. On Wednesday, the moon adds another striking element by passing closest to the grouping. The larger pattern continues beyond this week. Skywatching references for November 2026 show Mars and Jupiter tightening their spacing through midmonth, with Mars then passing close to Regulus in the days after. On Nov. 22, the three are expected to form a particularly clear triangle in Leo, and from Nov. 24 to 27 Mars makes a close pass by Regulus, highlighting the color contrast between reddish Mars and blue-white Regulus. This kind of alignment is not a physical encounter but an apparent grouping caused by the planets and moon traveling near the same path in the sky. Regulus, which lies close to the ecliptic, often serves as a marker for these meetings. So the answer is mixed: the current display is special and photogenic, but it is also one phase of a longer, active run of conjunctions and close pairings in Leo that will keep evolving through November.

Nov. 2–4 brings the week’s main sky show: the waning Moon passes 1.1° south of Mars, 0.5° south of Jupiter and 0.8° south of Regulus in successive mornings.
By 5–6 a.m. local time, the trio in Leo is high in the southeast, with Jupiter at magnitude -2.0 the brightest marker and the Moon shifting about 14° east in a day.
On Nov. 4, Mercury reaches inferior conjunction at 9 a.m. EST, leaving it hard to spot for about another week before it returns to the morning sky after the 11th.
That same morning, Venus shines at magnitude -4.4 about 2° south of Spica, while its 58-arcsecond disk appears as a 5%-lit crescent through a telescope.
The sequence extends an earlier Jupiter-Mars-Regulus alignment and gives early risers a compact run of changing dawn targets across Leo and Virgo.
