A fireball with an impact energy of 0.38 kilotons (380 tons of TNT equivalent) was detected at 22:26 UTC on September 13, 2025, at an altitude of 22.8 km (14.2 miles) over central Argentina. The event was observed from multiple provinces and produced a persistent trail and visible fragmentation.
A newly discovered comet, designated SWAN25B, emerged from behind the Sun in early September 2025 and was added to the Minor Planet Center’s Possible Comet Confirmation Page on September 12. The object is currently reported at magnitude 8.3 in MPC data, with independent amateur estimates placing it slightly brighter at magnitude 7.4–7.5. Orbit calculations are still in progress.
A bright daylight fireball was recorded at 17:49 UTC (14:49 LT) on September 9, 2025, over the Atlantic Ocean, off the northeastern coast of Brazil. NASA’s CNEOS data show the object released 0.44 kilotons of impact energy at an altitude of 24 km (15 miles). IMO and AMS received 10 reports from Ceará, with witnesses describing orange to blue colors, persistent trails, fragmentation, and sounds ranging from faint hissing to thunder-like booms.
A newly discovered asteroid designated 2025 QD8 will fly past Earth at a distance of 0.5 LD (0.00146 AU / 218 351 km / 135 677 miles) from the center of our planet at 14:58 UTC on September 3, 2025.
A total lunar eclipse will occur on September 7, 2025, and be visible to over 5 billion people across Africa, Europe, Asia, and Australia. The totality will last 82 minutes, making it the longest total lunar eclipse since 2022.
A newly discovered asteroid designated 2025 QO7 will fly past Earth at a distance of 0.7 LD (0.00182 AU / 271 500 km / 168 700 miles) from the center of our planet at around 14:09 UTC (±00:55) on August 31, 2025. The flyby will take place at a relative velocity of 8.17 km/s.
A bright fireball lit up the night sky over southern Japan at 23:08 JST (14:08 UTC) on August 19, 2025, releasing an estimated 1.6 kilotons of energy as it disintegrated over the Pacific Ocean southeast of Kyushu.
A bright fireball observed across Victoria, Australia just after 09:30 UTC (19:30 LT) on August 10, 2025, generated a loud sonic boom before breaking apart at low altitude. Few days later, scientists have identified a likely fall zone northeast of Maryborough, between Ballarat and Bendigo.
A newly discovered asteroid designated 2025 PU1 flew past Earth at a minimum distance of 0.08 LD (0.00218 AU / 29 300 km / 18 200 miles) from the center of our planet at 19:44 UTC on August 13, 2025.
A bright fireball meteor was observed over western and central Victoria, Australia, at 19:30 local time (LT) on August 10, 2025, producing a loud sonic boom that shook buildings and rattled windows across the region.
