Key Facts

Overview

1999 JK132 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1999 JK132 as potentially hazardous because its orbit does not bring it close to Earth.

1999 JK132 orbits the sun every 90,100 days (246.68 years), coming as close as 32.83 AU and reaching as far as 45.85 AU from the sun. Based on its brightness and the way it reflects light, 1999 JK132 is probably between 38.597 to 86.306 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.

No Close Approaches

1999 JK132's orbit is 31.90 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

1999 JK132's orbit is determined by observations dating back to May 10, 1999. It was last officially observed on May 19, 1999. The IAU Minor Planet Center records 4 observations used to determine its orbit.

Accessibility and Exploration

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