Key Facts


2016 XK24 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 XK24 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.

2016 XK24 orbits the sun every 161 days (0.44 years), coming as close as 0.15 AU and reaching as far as 1.01 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2016 XK24 is probably between 0.220 to 0.492 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

No Close Approaches

2016 XK24's orbit is 0.13 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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2016 XK24's orbit is determined by observations dating back to Dec. 11, 2016. It was last officially observed on Dec. 12, 2016. The IAU Minor Planet Center records 7 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
