Overview

585310 (2017 YZ1) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 YZ1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 YZ1 orbits the sun every 559 days (1.53 years), coming as close as 0.88 AU and reaching as far as 1.77 AU from the sun. Based on its brightness and the way it reflects light, 2017 YZ1 is probably between 0.218 to 0.488 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2017 YZ1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2017 YZ1 has 8 close approaches predicted in the coming decades:
