Key Facts

Overview

2017 OG69 is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2017 OG69 as potentially hazardous because its orbit does not bring it close to Earth.

2017 OG69 orbits the sun every 93,800 days (256.81 years), coming as close as 37.23 AU and reaching as far as 43.59 AU from the sun. Based on its brightness and the way it reflects light, 2017 OG69 is probably between 171.615 to 383.743 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.

No Close Approaches

2017 OG69's orbit is 36.30 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

2017 OG69's orbit is determined by observations dating back to Aug. 28, 2008. It was last officially observed on Nov. 2, 2022. The IAU Minor Planet Center records 48 observations used to determine its orbit.

Accessibility and Exploration

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