2015 WZ12 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2015 WZ12 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.
2015 WZ12 orbits the sun every 224 days (0.61 years), coming as close as 0.42 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2015 WZ12 is probably between 0.015 to 0.033 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2015 WZ12'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.
2015 WZ12 has 29 close approaches predicted in the coming decades:
