85774 (1998 UT18) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1998 UT18 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
1998 UT18 orbits the sun every 607 days (1.66 years), coming as close as 0.94 AU and reaching as far as 1.86 AU from the sun. 1998 UT18 is about 0.9 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 1998 UT18 has been observed. It completes a rotation on its axis every 55.00 hours.
1998 UT18'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.
