Overview

• The first supermoon of 2025 is due Oct. 6–7, appearing larger and brighter than usual and boosting skyglow that can wash out faint meteors.
• The Draconid meteors run Oct. 6–10 with a peak around Oct. 8, though visibility is expected to be poor because of the nearby full Moon.
• The Orionids are forecast to peak near Oct. 21 under a new moon, with NASA estimating about 20 meteors per hour in dark conditions.
• Comet C/2025 K1 (Tsuchinshan–ATLAS) reaches perihelion on Oct. 8 and may be a binocular target from dark sites, while interstellar comet 3I/ATLAS is tracked toward a late‑month perihelion near Oct. 30.
• Outreach ramps up with International Observe the Moon Night on Oct. 4 at planetariums in La Plata and Buenos Aires, a NASA‑scanned Moon replica touring Querétaro throughout October, and Mercury’s greatest eastern elongation set for Oct. 29.
