Key Facts

Overview

Baboquivari is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Baboquivari 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.

Baboquivari orbits the sun every 1,570 days (4.30 years), coming as close as 1.24 AU and reaching as far as 4.05 AU from the sun. Based on its brightness and the way it reflects light, Baboquivari is probably between 1.700 to 3.802 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of Baboquivari has been observed. It completes a rotation on its axis every 129.47 hours.

No Close Approaches

Baboquivari's orbit is 0.25 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

Baboquivari's orbit is determined by observations dating back to Oct. 16, 1963. It was last officially observed on April 15, 2021. The IAU Minor Planet Center records 1,448 observations used to determine its orbit.

Accessibility and Exploration

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