Overview

2019 OO is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 OO as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 OO orbits the sun every 764 days (2.09 years), coming as close as 0.81 AU and reaching as far as 2.46 AU from the sun. Based on its brightness and the way it reflects light, 2019 OO is probably between 0.151 to 0.337 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2019 OO's orbit is 0.04 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.

2019 OO has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Aug. 14, 2088 28,943,347 18.455
Aug. 15, 2111 26,592,663 18.642
Aug. 15, 2134 27,054,921 18.603

Images and Observations

2019 OO's orbit is determined by observations dating back to July 5, 2019. It was last officially observed on Jan. 26, 2022. The IAU Minor Planet Center records 76 observations used to determine its orbit.
