2019 SD8 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 SD8 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 SD8 orbits the sun every 853 days (2.34 years), coming as close as 0.88 AU and reaching as far as 2.65 AU from the sun. Based on its brightness and the way it reflects light, 2019 SD8 is probably between 0.009 to 0.020 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2019 SD8'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 SD8 has 10 close approaches predicted in the coming decades:
