Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Rhode Island (45.81 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Bressole orbits the sun every 1,830 days (5.01 years), coming as close as 2.46 AU and reaching as far as 3.40 AU from the sun. Bressole is about 45.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Bressole has been observed. It completes a rotation on its axis every 31.81 hours.

No Close Approaches

Bressole's orbit is 1.46 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

Bressole's orbit is determined by observations dating back to Dec. 2, 1931. It was last officially observed on June 16, 2023. The IAU Minor Planet Center records 3,927 observations used to determine its orbit.

Accessibility and Exploration

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