Overview

• Saturn is now well placed in the evening after its late‑September opposition, with the ring opening angle near 1°–1.5° and shrinking through November.
• Dwarf planet Ceres reaches opposition on October 2 at about magnitude 7.6, making it a straightforward binocular target under dark skies.
• The Orionid meteor shower peaks around October 21 under a new moon, with typical rates near 20 meteors per hour reported by meteor organizations.
• Comet C/2025 A6 (Lemmon) is forecast to brighten rapidly through October and comes closest to Earth on October 21, while C/2025 R2 (SWAN) passes around October 20 and likely requires optical aid.
• Near‑Earth asteroid (433) Eros returns to favorable view with opposition on October 29 before a closer approach in late November (~0.398 AU on November 30); the October full “Harvest Moon” on October 7 is the year’s first supermoon.
