2023 FY3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 FY3 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2023 FY3 orbits the sun every 404 days (1.11 years), coming as close as 1.00 AU and reaching as far as 1.14 AU from the sun. Based on its brightness and the way it reflects light, 2023 FY3 is probably between 0.003 to 0.012 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2023 FY3's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2023 FY3 has 9 close approaches predicted in the coming decades:

NASA Sentry has assessed impact risk for 3 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
|Date||Probability of Impact (%)||Impact Energy (Mt)|
|Aug. 11, 2114||0.00015||0.002904|
|May 31, 2116||0.00008||0.002908|
|July 20, 2114||0.00003||0.002908|
2023 FY3's orbit is determined by observations dating back to March 25, 2023. It was last officially observed on April 24, 2023. The IAU Minor Planet Center records 177 observations used to determine its orbit.
2023 FY3 can be reached with a journey of 394 days. This trajectory would require a delta-v of 3.413 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 2,866,786 potential trajectories and launch windows to this asteroid.
