2019 AE3 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 AE3 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 AE3 orbits the sun every 362 days (0.99 years), coming as close as 0.90 AU and reaching as far as 1.09 AU from the sun. Based on its brightness and the way it reflects light, 2019 AE3 is probably between 0.006 to 0.026 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 AE3's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2019 AE3's orbit is determined by observations dating back to Jan. 3, 2019. It was last officially observed on Jan. 5, 2019. The IAU Minor Planet Center records 23 observations used to determine its orbit.
2019 AE3 can be reached with a journey of 362 days. This trajectory would require a delta-v of 9.841 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 7,179 potential trajectories and launch windows to this asteroid.
