Kressmannia

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Baltimore (15.43 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Kressmannia orbits the sun every 1,190 days (3.26 years), coming as close as 1.75 AU and reaching as far as 2.63 AU from the sun. Kressmannia is about 15.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Baltimore.

The rotation of Kressmannia has been observed. It completes a rotation on its axis every 4.46 hours.

No Close Approaches

Kressmannia's orbit is 0.74 AU from Earth's orbit at its closest point. This means that there is a very 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

Kressmannia's orbit is determined by observations dating back to Feb. 9, 1905. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 4,517 observations used to determine its orbit.
