Overview

Oljato is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Oljato as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

Oljato orbits the sun every 1,170 days (3.20 years), coming as close as 0.63 AU and reaching as far as 3.73 AU from the sun. Its orbit is highly elliptical. Oljato is about 1.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of Oljato has been observed. It completes a rotation on its axis every 26.00 hours.

Oljato's spectral type None (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .

Close Approaches

Oljato's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

Oljato has 10 close approaches predicted in the coming decades:
