Key Facts

Overview

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

Giovannipratesi orbits the sun every 1,700 days (4.65 years), coming as close as 2.12 AU and reaching as far as 3.46 AU from the sun. Giovannipratesi is about 15.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Baltimore.

The rotation of Giovannipratesi has been observed. It completes a rotation on its axis every 14.12 hours.

Giovannipratesi's spectral type None (Tholen) / Ch (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Giovannipratesi's orbit is 1.14 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

Giovannipratesi's orbit is determined by observations dating back to Nov. 30, 1953. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 2,827 observations used to determine its orbit.

Accessibility and Exploration

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