199145 (2005 YY128) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2005 YY128 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2005 YY128 orbits the sun every 774 days (2.12 years), coming as close as 0.44 AU and reaching as far as 2.86 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2005 YY128 is probably between 0.584 to 1.306 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
2005 YY128'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.
2005 YY128 has 12 close approaches predicted in the coming decades:
