Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to the U.S. Capitol building
  • Classified as a Near Earth Asteroid (NEA)
  • Classified as a Potentially Hazardous Asteroid (PHA)
  • See orbit simulation


68347 (2001 KB67) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 KB67 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 KB67 orbits the sun every 345 days (0.94 years), coming as close as 0.60 AU and reaching as far as 1.33 AU from the sun. Based on its brightness and the way it reflects light, 2001 KB67 is probably between 0.278 to 0.622 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

The rotation of 2001 KB67 has been observed. It completes a rotation on its axis every 6.35 hours.

No Close Approaches

2001 KB67's orbit is 0.01 AU from Earth's orbit at its closest point. This means that there is an 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

2001 KB67's orbit is determined by observations dating back to May 30, 2001. It was last officially observed on June 24, 2020. The IAU Minor Planet Center records 594 observations used to determine its orbit.

Accessibility and Exploration

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