Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to the Golden Gate Bridge
  • Will pass within 3,724,892 km of Earth in 2019
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2019 QZ3 is a very 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 482 days (1.32 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 0.200 to 0.880 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the Golden Gate Bridge.

Close Approaches

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 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Sept. 9, 2019 3,724,892 7.468
Aug. 28, 2044 27,112,574 10.810
Sept. 12, 2065 5,102,900 6.836
Sept. 12, 2119 3,229,678 7.053

Images and Observations

2019 QZ3's orbit is determined by observations dating back to Aug. 20, 2019. It was last officially observed on Sept. 7, 2019. The IAU Minor Planet Center records 86 observations used to determine its orbit.

Accessibility and Exploration

2019 QZ3 can be reached with a journey of 362 days. This trajectory would require a delta-v of 10.198 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 267 potential trajectories and launch windows to this asteroid.
