Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a school bus or smaller
  • Will pass within 23,586,211 km of Earth in 2022
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2009 JF1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2009 JF1 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2009 JF1 orbits the sun every 952 days (2.61 years), coming as close as 0.50 AU and reaching as far as 3.29 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2009 JF1 is probably between 0.007 to 0.017 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2009 JF1's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2009 JF1 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
May 15, 2022 23,586,211 19.336
