Atami is a large asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Atami as potentially hazardous because its orbit does not bring it close to Earth.
Atami orbits the sun every 993 days (2.72 years), coming as close as 1.45 AU and reaching as far as 2.45 AU from the sun. Based on its brightness and the way it reflects light, Atami is probably between 8.027 to 17.949 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Boston.
The rotation of Atami has been observed. It completes a rotation on its axis every 27.45 hours.
Atami's orbit is 0.47 AU from Earth's orbit at its closest point. This means that there is a 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.
Atami's orbit is determined by observations dating back to Dec. 1, 1929. It was last officially observed on July 5, 2023. The IAU Minor Planet Center records 3,494 observations used to determine its orbit.
