Tacchini

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (6.47 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Tacchini orbits the sun every 1,580 days (4.33 years), coming as close as 2.58 AU and reaching as far as 2.74 AU from the sun. Tacchini is about 6.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

No Close Approaches

Tacchini's orbit is 1.57 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

Tacchini's orbit is determined by observations dating back to Aug. 22, 1949. It was last officially observed on July 1, 2023. The IAU Minor Planet Center records 2,850 observations used to determine its orbit.

Accessibility and Exploration

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