Key Facts

  • Categorized as a Amor-class Asteroid
  • Comparable in size to the island of Manhattan (4.30 km diameter)
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


Bede is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Bede as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

Bede orbits the sun every 863 days (2.36 years), coming as close as 1.27 AU and reaching as far as 2.28 AU from the sun. Bede is about 4.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of Bede has been observed. It completes a rotation on its axis every 226.80 hours.

Bede's spectral type None (Tholen) / Xc (SMASSII) indicates that it is likely to contain iron, nickel, cobalt, and platinum.

No Close Approaches

Bede's orbit is 0.35 AU from Earth's orbit at its closest point. This means that there is a 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

Bede's orbit is determined by observations dating back to June 9, 1975. It was last officially observed on July 7, 2022. The IAU Minor Planet Center records 3,674 observations used to determine its orbit.

Accessibility and Exploration

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