2016 YN4 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 YN4 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.
2016 YN4 orbits the sun every 1,410 days (3.86 years), coming as close as 0.71 AU and reaching as far as 4.21 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2016 YN4 is probably between 0.305 to 0.682 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to the U.S. Capitol building.
2016 YN4's orbit is 0.08 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.
