Key Facts

Overview

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

Platzeck orbits the sun every 1,910 days (5.23 years), coming as close as 2.71 AU and reaching as far as 3.31 AU from the sun. Platzeck is about 19.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

The rotation of Platzeck has been observed. It completes a rotation on its axis every 6.00 hours.

No Close Approaches

Platzeck's orbit is 1.74 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

Platzeck's orbit is determined by observations dating back to March 27, 1906. It was last officially observed on July 2, 2023. The IAU Minor Planet Center records 5,506 observations used to determine its orbit.

Accessibility and Exploration

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