Magnitude 0.8 Mars stands at the border of Cancer and Leo, tracking eastward to form a predawn planetary alignment with bright Jupiter and the star Regulus.
The Predawn Alignment of Mars, Jupiter, and Regulus
Tracking eastward through the sky, Mars currently stands within the bounds of the Crab at roughly 60° high in the southeast. It is positioned just over 6° to the upper right of brighter Jupiter in Leo, roughly 90 minutes before sunrise. To Jupiter’s east sits magnitude 1.4 Regulus, the brightest star in the Lion which serves as the great cat’s heart. Together, Jupiter, Mars, and Regulus form a distinct line slashing upward in the predawn sky.
Far to the planetary pair’s upper right is Procyon, the bright nose of Canis Minor, the Little Dog. To that star’s far lower right shines even brighter Sirius, the nose of Canis Major, the Big Dog, which holds the title of the brightest star in the sky. However, Jupiter commands a magnitude of –2.0, currently outshining Sirius and its magnitude –1.4 glow.
Planetary Position Shift Into Leo
Mars will continue its eastward journey through the cosmos, crossing the line to join Jupiter in Leo by tomorrow morning. This shift brings the Red Planet directly onto the border of Cancer and Leo, setting up a shared celestial space within the Lion. Alison Klesman, senior editor of Astronomy magazine and a Ph.D. holder in astronomy who has studied topics ranging from minor planets to supermassive black holes, detailed the ongoing movements in the publication’s full Sky This Week column.
Earlier observations noted the open cluster Collinder 463 at magnitude 0.8 on October 29 as Mars advanced along its trajectory. Local conditions for tracking the event on October 30, 2026, include a sunrise at 7:27 A.M., a sunset at 6:00 P.M., a moonrise at 9:53 P.M., and a moonset at 12:45 P.M., with a waning gibbous moon at 69% illumination recorded at 10 P.M. local time from 40° N 90° W.
