66407 (1999 LQ28) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1999 LQ28 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.
1999 LQ28 orbits the sun every 479 days (1.31 years), coming as close as 1.05 AU and reaching as far as 1.34 AU from the sun. Based on its brightness and the way it reflects light, 1999 LQ28 is probably between 0.441 to 0.986 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.
1999 LQ28's orbit is 0.10 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.
1999 LQ28 has 9 close approaches predicted in the coming decades:
