Key Facts

Overview

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

Bredehoft orbits the sun every 1,240 days (3.39 years), coming as close as 2.10 AU and reaching as far as 2.41 AU from the sun. Bredehoft is about 3.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

No Close Approaches

Bredehoft's orbit is 1.08 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

Bredehoft's orbit is determined by observations dating back to Nov. 23, 1990. It was last officially observed on June 17, 2023. The IAU Minor Planet Center records 2,642 observations used to determine its orbit.

Accessibility and Exploration

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