9440 (1997 FZ1) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1997 FZ1 as potentially hazardous because its orbit does not bring it close to Earth.
1997 FZ1 orbits the sun every 1,350 days (3.70 years), coming as close as 2.04 AU and reaching as far as 2.74 AU from the sun. Based on its brightness and the way it reflects light, 1997 FZ1 is probably between 2.969 to 6.638 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.
The rotation of 1997 FZ1 has been observed. It completes a rotation on its axis every 5.20 hours.
1997 FZ1's orbit is 1.04 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
1997 FZ1's orbit is determined by observations dating back to Feb. 25, 1982. It was last officially observed on June 22, 2023. The IAU Minor Planet Center records 2,609 observations used to determine its orbit.
