2018 DA2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2018 DA2 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 DA2 orbits the sun every 303 days (0.83 years), coming as close as 0.48 AU and reaching as far as 1.28 AU from the sun. Based on its brightness and the way it reflects light, 2018 DA2 is probably between 0.058 to 0.130 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2018 DA2's orbit is 0.08 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.
2018 DA2 has 12 close approaches predicted in the coming decades:
