2018 NC is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 NC as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2018 NC orbits the sun every 1,080 days (2.96 years), coming as close as 0.82 AU and reaching as far as 3.30 AU from the sun. Based on its brightness and the way it reflects light, 2018 NC is probably between 0.210 to 0.470 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2018 NC's orbit is 0.04 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.
2018 NC has 8 close approaches predicted in the coming decades:
