Key Facts

Overview

614688 (2011 KN36) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2011 KN36 as potentially hazardous because its orbit does not bring it close to Earth.

2011 KN36 orbits the sun every 104,000 days (284.74 years), coming as close as 40.95 AU and reaching as far as 45.47 AU from the sun. Based on its brightness and the way it reflects light, 2011 KN36 is probably between 110.295 to 246.627 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.

No Close Approaches

2011 KN36's orbit is 39.90 AU from Earth's orbit at its closest point. This means that there is an extremely 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

2011 KN36's orbit is determined by observations dating back to Dec. 24, 2003. It was last officially observed on Jan. 29, 2022. The IAU Minor Planet Center records 25 observations used to determine its orbit.

Accessibility and Exploration

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