2021 GU6 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2021 GU6 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.
2021 GU6 orbits the sun every 223 days (0.61 years), coming as close as 0.38 AU and reaching as far as 1.06 AU from the sun. Based on its brightness and the way it reflects light, 2021 GU6 is probably between 0.014 to 0.031 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2021 GU6's orbit is 0.03 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.
2021 GU6 has 14 close approaches predicted in the coming decades:
