65690 (1991 DG) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1991 DG as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1991 DG orbits the sun every 623 days (1.71 years), coming as close as 0.91 AU and reaching as far as 1.95 AU from the sun. Based on its brightness and the way it reflects light, 1991 DG is probably between 0.421 to 0.942 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
1991 DG's orbit is 0.04 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.
1991 DG has 11 close approaches predicted in the coming decades:
