2021 AF8 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2021 AF8 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2021 AF8 orbits the sun every 1,050 days (2.87 years), coming as close as 0.98 AU and reaching as far as 3.06 AU from the sun. Based on its brightness and the way it reflects light, 2021 AF8 is probably between 0.240 to 0.537 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.
2021 AF8'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.
2021 AF8 has 4 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|May 4, 2021||3,360,369||9.406|
|June 4, 2041||23,476,415||13.291|
|May 15, 2107||5,688,976||9.876|
|March 25, 2130||19,804,360||11.499|
2021 AF8's orbit is determined by observations dating back to Dec. 1, 2014. It was last officially observed on July 9, 2021. The IAU Minor Planet Center records 394 observations used to determine its orbit.
