Key Facts

Overview

119951 (2002 KX14) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2002 KX14 as potentially hazardous because its orbit does not bring it close to Earth.

2002 KX14 orbits the sun every 88,000 days (240.93 years), coming as close as 36.89 AU and reaching as far as 40.55 AU from the sun. Based on its brightness and the way it reflects light, 2002 KX14 is probably between 303.777 to 679.266 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of Iowa.

No Close Approaches

2002 KX14's orbit is 35.90 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

2002 KX14's orbit is determined by observations dating back to May 31, 1984. It was last officially observed on Aug. 3, 2018. The IAU Minor Planet Center records 245 observations used to determine its orbit.

Accessibility and Exploration

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