Key Facts

Overview

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

Manto orbits the sun every 1,290 days (3.53 years), coming as close as 1.71 AU and reaching as far as 2.94 AU from the sun. Manto is about 13.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of Manto has been observed. It completes a rotation on its axis every 122.30 hours.

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

No Close Approaches

Manto's orbit is 0.70 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.

Images and Observations

Manto's orbit is determined by observations dating back to May 12, 1917. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 9,419 observations used to determine its orbit.
