2018 HU is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2018 HU 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.
2018 HU orbits the sun every 269 days (0.74 years), coming as close as 0.52 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2018 HU is probably between 0.019 to 0.043 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 HU's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2018 HU has 10 close approaches predicted in the coming decades:
