Daihoji

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (9.62 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Daihoji is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Daihoji as potentially hazardous because its orbit does not bring it close to Earth.

Daihoji orbits the sun every 2,020 days (5.53 years), coming as close as 2.55 AU and reaching as far as 3.70 AU from the sun. Daihoji is about 9.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Daihoji has been observed. It completes a rotation on its axis every 22.55 hours.

No Close Approaches

Daihoji's orbit is 1.64 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.

Images and Observations

Daihoji's orbit is determined by observations dating back to June 1, 1994. It was last officially observed on June 12, 2022. The IAU Minor Planet Center records 1,054 observations used to determine its orbit.
