514150 (2015 KJ57) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 KJ57 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 KJ57 orbits the sun every 711 days (1.95 years), coming as close as 0.93 AU and reaching as far as 2.19 AU from the sun. Based on its brightness and the way it reflects light, 2015 KJ57 is probably between 0.131 to 0.294 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
2015 KJ57's orbit is 0.01 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.
2015 KJ57 has 12 close approaches predicted in the coming decades:
