A/2019 O3 is a large asteroid with an orbit not bound to the sun. NASA JPL has not classified A/2019 O3 as potentially hazardous because its orbit does not bring it close to Earth.
A/2019 O3 orbits the sun every 0 days (0.00 years), coming as close as -0.00 AU and reaching as far as -8608000.00 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, A/2019 O3 is probably between 31.956 to 71.456 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
A/2019 O3's orbit is 8.28 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.
A/2019 O3's orbit is determined by observations dating back to July 10, 2019. It was last officially observed on Dec. 1, 2019. The IAU Minor Planet Center records 74 observations used to determine its orbit.
