Key Facts

Overview

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

Wieck orbits the sun every 1,910 days (5.23 years), coming as close as 2.84 AU and reaching as far as 3.19 AU from the sun. Wieck is about 9.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Wieck has been observed. It completes a rotation on its axis every 10.06 hours.

No Close Approaches

Wieck's orbit is 1.85 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

Wieck's orbit is determined by observations dating back to Oct. 13, 1980. It was last officially observed on Feb. 9, 2023. The IAU Minor Planet Center records 3,626 observations used to determine its orbit.

Accessibility and Exploration

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