Overview
2019 FM2 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 FM2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2019 FM2 orbits the sun every 351 days (0.96 years), coming as close as 0.71 AU and reaching as far as 1.24 AU from the sun. Based on its brightness and the way it reflects light, 2019 FM2 is probably between 0.201 to 0.449 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2019 FM2'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 FM2 has 23 close approaches predicted in the coming decades:
