A Car-Sized Asteroid is Approaching Earth
Just three days after its discovery, asteroid 2026 FM3 will make a remarkably close approach to Earth late tonight, March 24th. This event highlights the ongoing efforts to track and understand near-Earth objects (NEOs).
Close Encounter Details
The close encounter will occur at 10:07 p.m. EDT (0207 GMT on March 25). The asteroid, estimated to be between 4-8 meters (13-26 feet) in diameter, will pass a mere 147,836 miles (237,918 kilometers) from Earth’s southern hemisphere. That’s only 61.9% of the distance to the moon!
Traveling at a swift 11,461 miles per hour (18,444 kilometers per hour), 2026 FM3 will then zip past the moon approximately three hours later, at a distance of 370,022 miles (595,492 km). Fortunately, NASA confirms this asteroid poses absolutely no threat to either Earth or the Moon.
Orbital Path and Past Encounters
Initial observations reveal that 2026 FM3 follows a nearly circular orbit around the sun, intersecting Earth’s orbit twice during its 354-day period. Interestingly, its closest known approach to Earth occurred way back in September 1965, when it missed our planet by a relatively close 30,559 miles (49,181 km).
However, current data indicates that 2026 FM3 won’t make any similarly close approaches to Earth within the next 100 years. Furthermore, due to its size, it isn’t classified as a potentially hazardous asteroid by NASA’s Center for Near Earth Object Studies (https://cneos.jpl.nasa.gov/).
Earth’s Protective Shield & Future Discoveries
Earth’s atmosphere provides a crucial defense against smaller asteroids. These often burn up as meteors, creating the beautiful “shooting stars” we sometimes observe. Larger debris can result in spectacular fireballs, as recently witnessed over Ohio and Texas, occasionally scattering fragments onto the ground.
2026 FM3 is just one of over 41,000 near-Earth asteroids discovered to date. This number is expected to grow significantly with the advent of powerful new observatories like the Vera Rubin Observatory, which has already identified 2,000 previously unknown asteroids in its initial data.
