2019 CN2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 CN2 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 CN2 orbits the sun every 319 days (0.87 years), coming as close as 0.71 AU and reaching as far as 1.12 AU from the sun. Based on its brightness and the way it reflects light, 2019 CN2 is probably between 0.004 to 0.016 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 CN2'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 CN2 has 16 close approaches predicted in the coming decades:

2019 CN2's orbit is determined by observations dating back to Feb. 4, 2019. It was last officially observed on Feb. 9, 2019. The IAU Minor Planet Center records 23 observations used to determine its orbit.
2019 CN2 can be reached with a journey of 378 days. This trajectory would require a delta-v of 9.357 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 24,968 potential trajectories and launch windows to this asteroid.
