Attention night sky watchers and planetary preparedness enthusiasts: September’s cosmic forecast reads like disaster cinema mixed with a science special. On the 18th, asteroid 2025 FA22 will fly by Earth at about 10.8 km/s—less than 900,000 kilometers from our surface, roughly 2.2 times the distance to the Moon. Experts say there’s no threat of impact this time. Still, this close call doesn’t inspire restful sleep, especially amid what’s turning into an “asteroid wave.”
Yet, 2025 FA22 isn’t alone in attracting attention. Recently discovered comet SWAN 25B is brightening quickly, nearing visibility to the naked eye. It shines brightly against the backdrop of numerous asteroids making unusually close approach. Add interstellar object 3I/ATLAS rushing toward its October 29, 2025, rendezvous with the inner solar system, and you get a planetary drama that captivates both space weather preppers and professional astronomers.
2025 FA22’s Close Flyby: Risk and Rarity
On September 18th, 2025 FA22 will perform a memorable drive-by, confirmed by live observation campaigns. With a diameter of about 520 feet and a speed of 10.8 km/s, it meets the criteria for a potentially hazardous near-Earth object (NEO). However, astronomers emphasize that FA22’s trajectory keeps us well outside the danger zone this orbit. (Take a breath, but maybe keep that survival gear handy—history shows close calls can have unexpected results.)

The asteroid’s passage, tracked by NASA and observatories worldwide, falls into the “no collision, but worth tracking” category. As India Today reports, objects larger than 140 meters can cause significant regional damage upon impact. As such, 2025 FA22 earns a spot on the global planetary defense watchlist. Consider this a fire drill for the solar system, reinforcing the importance of continuous near-Earth object monitoring.
A Surge of Asteroids and Comet SWAN 25B Brightening Fast
September isn’t an isolated case; astronomers report a surge in close asteroid flybys, dubbing it an “asteroid wave.” Data from sources like NASA’s NEO surveillance project indicates multiple objects, some as small as 20 meters, will pass within lunar distances over just a few days. This frequency far exceeds the monthly average, drawing attention from veteran skywatchers. They recall how even relatively small impactors can cause significant issues, as explored in .
