Key Facts

Overview

Francette is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Francette as potentially hazardous because its orbit does not bring it close to Earth.

Francette orbits the sun every 2,870 days (7.86 years), coming as close as 3.20 AU and reaching as far as 4.70 AU from the sun. Francette is about 76.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Francette has been observed. It completes a rotation on its axis every 32.78 hours.

Francette's spectral type P (Tholen) / X (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Francette's orbit is 2.21 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

Francette's orbit is determined by observations dating back to Dec. 3, 1931. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 5,141 observations used to determine its orbit.

Accessibility and Exploration

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