Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to a school bus or smaller
  • Will pass within 1,322,970 km of Earth in 2020
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2020 DF is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2020 DF 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.

2020 DF orbits the sun every 242 days (0.66 years), coming as close as 0.51 AU and reaching as far as 1.02 AU from the sun. Based on its brightness and the way it reflects light, 2020 DF is probably between 0.015 to 0.034 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 DF's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2020 DF has 7 close approaches predicted in the coming decades:
