  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

2020 CK2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 CK2 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 CK2 orbits the sun every 654 days (1.79 years), coming as close as 0.97 AU and reaching as far as 1.98 AU from the sun. Based on its brightness and the way it reflects light, 2020 CK2 is probably between 0.002 to 0.011 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 CK2's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2020 CK2 has 2 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Feb. 11, 2020 476,510 5.455
Dec. 5, 2028 26,600,910 10.778
