2020 OM is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 OM 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.
2020 OM orbits the sun every 219 days (0.60 years), coming as close as 0.38 AU and reaching as far as 1.04 AU from the sun. Based on its brightness and the way it reflects light, 2020 OM is probably between 0.011 to 0.024 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2020 OM's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.
2020 OM has 35 close approaches predicted in the coming decades:
