Key Facts

  • Categorized as a Main-belt Asteroid
  • Comparable in size to the U.S. state of Rhode Island (50.51 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation


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

Budrosa orbits the sun every 1,820 days (4.98 years), coming as close as 2.86 AU and reaching as far as 2.97 AU from the sun. Budrosa is about 50.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Budrosa has been observed. It completes a rotation on its axis every 4.61 hours.

Budrosa's spectral type M (Tholen) / Xk (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.

No Close Approaches

Budrosa's orbit is 1.87 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

Budrosa's orbit is determined by observations dating back to Sept. 27, 1892. It was last officially observed on Aug. 8, 2021. The IAU Minor Planet Center records 2,912 observations used to determine its orbit.

Accessibility and Exploration

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