Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a football field
  • Will pass within 21,762,157 km of Earth in 2019
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2020 BN14 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 BN14 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 BN14 orbits the sun every 1,100 days (3.01 years), coming as close as 0.90 AU and reaching as far as 3.27 AU from the sun. Based on its brightness and the way it reflects light, 2020 BN14 is probably between 0.138 to 0.309 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2020 BN14's orbit is 0.07 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.

2020 BN14 has 6 close approaches predicted in the coming decades:
