Key Facts

Overview

2000 WL183 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2000 WL183 as potentially hazardous because its orbit does not bring it close to Earth.

2000 WL183 orbits the sun every 104,000 days (284.74 years), coming as close as 40.22 AU and reaching as far as 46.46 AU from the sun. Based on its brightness and the way it reflects light, 2000 WL183 is probably between 80.270 to 179.490 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.

No Close Approaches

2000 WL183's orbit is 39.20 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

2000 WL183's orbit is determined by observations dating back to Nov. 26, 2000. It was last officially observed on Dec. 21, 2006. The IAU Minor Planet Center records 17 observations used to determine its orbit.

Accessibility and Exploration

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