2019 AC3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 AC3 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 AC3 orbits the sun every 383 days (1.05 years), coming as close as 0.92 AU and reaching as far as 1.15 AU from the sun. Based on its brightness and the way it reflects light, 2019 AC3 is probably between 0.060 to 0.270 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 AC3's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.
2019 AC3 has 25 close approaches predicted in the coming decades:

2019 AC3's orbit is determined by observations dating back to Jan. 3, 2019. It was last officially observed on Oct. 29, 2019. The IAU Minor Planet Center records 48 observations used to determine its orbit.
2019 AC3 can be reached with a journey of 370 days. This trajectory would require a delta-v of 4.84 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 712,964 potential trajectories and launch windows to this asteroid.
