2004 FH is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 FH 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.
2004 FH orbits the sun every 271 days (0.74 years), coming as close as 0.58 AU and reaching as far as 1.06 AU from the sun. Based on its brightness and the way it reflects light, 2004 FH is probably between 0.013 to 0.056 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
The rotation of 2004 FH has been observed. It completes a rotation on its axis every 0.05 hours.
2004 FH's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2004 FH has 15 close approaches predicted in the coming decades:

2004 FH's orbit is determined by observations dating back to March 16, 2004. It was last officially observed on Feb. 19, 2021. The IAU Minor Planet Center records 269 observations used to determine its orbit.
2004 FH can be reached with a journey of 330 days. This trajectory would require a delta-v of 9.116 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 26,343 potential trajectories and launch windows to this asteroid.
