Key Facts


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

Ambrosia orbits the sun every 1,530 days (4.19 years), coming as close as 1.83 AU and reaching as far as 3.37 AU from the sun. Ambrosia is about 26.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Ambrosia has been observed. It completes a rotation on its axis every 6.58 hours.

Ambrosia's spectral type None (Tholen) / Sk (SMASSII) indicates that it is likely to contain and .

No Close Approaches

Ambrosia's orbit is 0.89 AU from Earth's orbit at its closest point. This means that there is an 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.

Images and Observations

Ambrosia's orbit is determined by observations dating back to Sept. 10, 1915. It was last officially observed on May 24, 2021. The IAU Minor Planet Center records 3,600 observations used to determine its orbit.

Scientists have been able to determine this object's shape.
