Key Facts

Overview

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

Andres Bello orbits the sun every 1,190 days (3.26 years), coming as close as 2.03 AU and reaching as far as 2.38 AU from the sun. Based on its brightness and the way it reflects light, Andres Bello is probably between 5.709 to 12.766 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of Andres Bello has been observed. It completes a rotation on its axis every 3.43 hours.

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

No Close Approaches

Andres Bello's orbit is 1.05 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

Andres Bello's orbit is determined by observations dating back to Aug. 29, 1962. It was last officially observed on June 21, 2023. The IAU Minor Planet Center records 3,580 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
