Overview

2019 FZ is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 FZ as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2019 FZ orbits the sun every 300 days (0.82 years), coming as close as 0.33 AU and reaching as far as 1.43 AU from the sun. Based on its brightness and the way it reflects light, 2019 FZ is probably between 0.142 to 0.318 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2019 FZ'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 FZ has 17 close approaches predicted in the coming decades:
