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

Overview

2016 KC is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2016 KC 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 collision.

2016 KC orbits the sun every 553 days (1.51 years), coming as close as 0.96 AU and reaching as far as 1.68 AU from the sun. Based on its brightness and the way it reflects light, 2016 KC is probably between 0.44 to 1.95 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. Pentagon.

Close Approaches

2016 KC's orbit is 0.04 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.

2016 KC has 10 close approaches predicted in the coming decades:

Images and Observations

2016 KC's orbit is determined by observations dating back to May 13, 2016. It was last officially observed on May 31, 2019. The IAU Minor Planet Center records 44 observations used to determine its orbit.

Accessibility and Exploration

2016 KC can be reached with a journey of 370 days. This trajectory would require a delta-v of 11.655 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 20 potential trajectories and launch windows to this asteroid.
