Overview

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

2019 FH orbits the sun every 690 days (1.89 years), coming as close as 0.34 AU and reaching as far as 2.71 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2019 FH is probably between 0.244 to 0.545 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

Close Approaches

2019 FH'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.

2019 FH has 14 close approaches predicted in the coming decades:
