Overview
2019 QG is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 QG as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 QG orbits the sun every 272 days (0.74 years), coming as close as 0.63 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2019 QG is probably between 0.142 to 0.318 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2019 QG's orbit is 0.05 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.
2019 QG has 18 close approaches predicted in the coming decades:
