Key Facts

Overview

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

Widemann orbits the sun every 1,970 days (5.39 years), coming as close as 2.69 AU and reaching as far as 3.46 AU from the sun. Widemann is about 9.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Widemann has been observed. It completes a rotation on its axis every 26.01 hours.

No Close Approaches

Widemann's orbit is 1.69 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

Widemann's orbit is determined by observations dating back to April 4, 1992. It was last officially observed on May 30, 2023. The IAU Minor Planet Center records 1,946 observations used to determine its orbit.

Accessibility and Exploration

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