Key Facts

Overview

2023 OL is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 OL as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2023 OL orbits the sun every 1,190 days (3.26 years), coming as close as 0.61 AU and reaching as far as 3.78 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2023 OL is probably between 0.212 to 0.474 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

No Close Approaches

2023 OL's orbit is 0.03 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

2023 OL's orbit is determined by observations dating back to June 18, 2023. It was last officially observed on July 28, 2023. The IAU Minor Planet Center records 52 observations used to determine its orbit.

Accessibility and Exploration

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