Bronshten

Key Facts

• Categorized as a Mars-crossing Asteroid
• Comparable in size to the island of Manhattan
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Bronshten is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified Bronshten as potentially hazardous because its orbit does not bring it close to Earth.

Bronshten orbits the sun every 1,320 days (3.61 years), coming as close as 1.57 AU and reaching as far as 3.14 AU from the sun. Based on its brightness and the way it reflects light, Bronshten is probably between 2.783 to 6.224 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of Bronshten has been observed. It completes a rotation on its axis every 2.67 hours.

No Close Approaches

Bronshten's orbit is 0.57 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

Bronshten's orbit is determined by observations dating back to July 26, 1971. It was last officially observed on Feb. 13, 2023. The IAU Minor Planet Center records 2,269 observations used to determine its orbit.

Accessibility and Exploration

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