Key Facts

Overview

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

Nabrown orbits the sun every 1,560 days (4.27 years), coming as close as 2.36 AU and reaching as far as 2.91 AU from the sun. Based on its brightness and the way it reflects light, Nabrown is probably between 2.562 to 5.728 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

No Close Approaches

Nabrown's orbit is 1.35 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

Nabrown's orbit is determined by observations dating back to March 25, 1971. It was last officially observed on May 26, 2022. The IAU Minor Planet Center records 1,439 observations used to determine its orbit.

Accessibility and Exploration

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