Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a school bus or smaller
  • Will pass within 392,096 km of Earth in 2022
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2022 EO is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2022 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.

2022 EO orbits the sun every 371 days (1.02 years), coming as close as 0.76 AU and reaching as far as 1.26 AU from the sun. Based on its brightness and the way it reflects light, 2022 EO is probably between 0.002 to 0.010 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2022 EO'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.

2022 EO has 8 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
March 5, 2022 392,096 8.509
March 6, 2023 14,526,744 5.643
Feb. 11, 2024 27,944,186 5.523
April 14, 2024 28,721,303 5.692
Sept. 23, 2031 14,528,194 5.757
Sept. 28, 2032 5,064,791 8.740
Oct. 3, 2033 19,677,708 12.077
Feb. 27, 2081 21,059,508 4.934

Images and Observations

2022 EO's orbit is determined by observations dating back to March 1, 2022. It was last officially observed on March 3, 2022. The IAU Minor Planet Center records 21 observations used to determine its orbit.

Accessibility and Exploration

2022 EO can be reached with a journey of 394 days. This trajectory would require a delta-v of 8.572 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 105,362 potential trajectories and launch windows to this asteroid.
