Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to the Golden Gate Bridge (0.55 km diameter)
  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation

Overview

231937 (2001 FO32) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 FO32 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 FO32 orbits the sun every 809 days (2.21 years), coming as close as 0.30 AU and reaching as far as 3.10 AU from the sun. Its orbit is highly elliptical. 2001 FO32 is about 0.6 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

No Close Approaches

2001 FO32's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2001 FO32's orbit is determined by observations dating back to March 23, 2001. It was last officially observed on March 22, 2021. The IAU Minor Planet Center records 211 observations used to determine its orbit.

Accessibility and Exploration

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