2019 QZ3 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 QZ3 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 QZ3 orbits the sun every 480 days (1.31 years), coming as close as 0.97 AU and reaching as far as 1.43 AU from the sun. Based on its brightness and the way it reflects light, 2019 QZ3 is probably between 0.190 to 0.850 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
2019 QZ3's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2019 QZ3 has 10 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Sept. 9, 2019||3,725,256||7.469|
|Oct. 1, 2040||24,383,784||6.709|
|Aug. 29, 2044||26,261,951||10.674|

2019 QZ3's orbit is determined by observations dating back to Aug. 20, 2019. It was last officially observed on Sept. 11, 2019. The IAU Minor Planet Center records 96 observations used to determine its orbit.
2019 QZ3 can be reached with a journey of 362 days. This trajectory would require a delta-v of 10.197 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 258 potential trajectories and launch windows to this asteroid.
