Key Facts


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

Beatrix orbits the sun every 1,390 days (3.81 years), coming as close as 2.23 AU and reaching as far as 2.63 AU from the sun. Beatrix is about 110.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.

The rotation of Beatrix has been observed. It completes a rotation on its axis every 10.11 hours.

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

No Close Approaches

Beatrix's orbit is 1.23 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

Beatrix's orbit is determined by observations dating back to May 13, 1865. It was last officially observed on Aug. 9, 2021. The IAU Minor Planet Center records 2,943 observations used to determine its orbit.

Accessibility and Exploration

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