Overview

2019 YZ3 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 YZ3 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 YZ3 orbits the sun every 848 days (2.32 years), coming as close as 0.71 AU and reaching as far as 2.80 AU from the sun. Based on its brightness and the way it reflects light, 2019 YZ3 is probably between 0.149 to 0.334 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2019 YZ3'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.

2019 YZ3 has 10 close approaches predicted in the coming decades:
