Hosamu is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Hosamu as potentially hazardous because its orbit does not bring it close to Earth.
Hosamu orbits the sun every 2,140 days (5.86 years), coming as close as 2.88 AU and reaching as far as 3.62 AU from the sun. Hosamu is about 12.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
Hosamu's orbit is 1.89 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.
Hosamu's orbit is determined by observations dating back to March 15, 1978. It was last officially observed on Feb. 10, 2023. The IAU Minor Planet Center records 2,542 observations used to determine its orbit.
