Sandashounkan is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Sandashounkan as potentially hazardous because its orbit does not bring it close to Earth.
Sandashounkan orbits the sun every 2,000 days (5.48 years), coming as close as 2.46 AU and reaching as far as 3.76 AU from the sun. Sandashounkan is about 7.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Sandashounkan has been observed. It completes a rotation on its axis every 33.62 hours.
Sandashounkan's orbit is 1.54 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.
Sandashounkan's orbit is determined by observations dating back to Dec. 22, 1954. It was last officially observed on June 22, 2023. The IAU Minor Planet Center records 2,607 observations used to determine its orbit.
