Mamiya is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Mamiya as potentially hazardous because its orbit does not bring it close to Earth.
Mamiya orbits the sun every 1,400 days (3.83 years), coming as close as 1.99 AU and reaching as far as 2.91 AU from the sun. Mamiya is about 11.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
The rotation of Mamiya has been observed. It completes a rotation on its axis every 7.87 hours.
Mamiya's orbit is 0.99 AU from Earth's orbit at its closest point. This means that there is a very 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.
Mamiya's orbit is determined by observations dating back to Sept. 4, 1972. It was last officially observed on Feb. 17, 2023. The IAU Minor Planet Center records 5,233 observations used to determine its orbit.
