Key Facts

Overview

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

Nirenberg orbits the sun every 1,340 days (3.67 years), coming as close as 1.89 AU and reaching as far as 2.86 AU from the sun. Nirenberg is about 7.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Nirenberg has been observed. It completes a rotation on its axis every 43.47 hours.

No Close Approaches

Nirenberg's orbit is 0.89 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

Nirenberg's orbit is determined by observations dating back to Feb. 21, 1980. It was last officially observed on Feb. 3, 2023. The IAU Minor Planet Center records 2,854 observations used to determine its orbit.
