Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to a school bus or smaller
  • Will pass within 7,023,905 km of Earth in 2019
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2019 EO is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2019 EO 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.

2019 EO orbits the sun every 362 days (0.99 years), coming as close as 0.47 AU and reaching as far as 1.52 AU from the sun. Based on its brightness and the way it reflects light, 2019 EO is probably between 0.061 to 0.136 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2019 EO's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2019 EO has 9 close approaches predicted in the coming decades:
