2023 FY3 is a near-Earth object roughly 5 meters (16 ft) in diameter discovered by K. W. Wierzchos observing with the 0.68-m Schmidt + 10K CCD of the Catalina Sky Survey.[1]
Details
The object orbits the Sun but makes slow close approaches to the Earth–Moon system. Due to its Earth-like orbit, the object might be of artificial origin or lunar ejecta. However, visible spectroscopy obtained with the Gran Telescopio Canarias shows that it is an asteroid.[5] The closest approach to Earth in 2023 was 24 March 2023 at roughly 0.00369 au (343,000 mi) when it had a relative velocity of 1.46 km/s (3,300 mph).[3]
