- Classified as a Near Earth Asteroid (NEA)
- Not a Potentially Hazardous Object
- See orbit simulation
Overview
2019 AQ3 is a mid-sized asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2019 AQ3 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
2019 AQ3 orbits the sun every 165 days (0.45 years), coming as close as 0.40 AU and reaching as far as 0.77 AU from the sun. Based on its brightness and the way it reflects light, 2019 AQ3 is probably between 0.844 to 1.888 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
No Close Approaches
2019 AQ3's orbit is 0.23 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
2019 AQ3's orbit is determined by observations dating back to Oct. 13, 2015. It was last officially observed on Feb. 2, 2023. The IAU Minor Planet Center records 144 observations used to determine its orbit.
