Key Facts

  • Categorized as a Apollo-class Asteroid
  • Comparable in size to a school bus or smaller
  • Will pass within 3,940,063 km of Earth in 2023
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


2012 KP24 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2012 KP24 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.

2012 KP24 orbits the sun every 671 days (1.84 years), coming as close as 0.95 AU and reaching as far as 2.06 AU from the sun. Based on its brightness and the way it reflects light, 2012 KP24 is probably between 0.014 to 0.030 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

The rotation of 2012 KP24 has been observed. It completes a rotation on its axis every 0.04 hours.
