Overview
2019 FJ is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 FJ as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 FJ orbits the sun every 243 days (0.67 years), coming as close as 0.30 AU and reaching as far as 1.23 AU from the sun. Based on its brightness and the way it reflects light, 2019 FJ is probably between 0.404 to 0.904 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2019 FJ's orbit is 0.02 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 FJ has 30 close approaches predicted in the coming decades:
