  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of New York (33.31 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

34642 (2000 WN2) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 WN2 as potentially hazardous because its orbit does not bring it close to Earth.

2000 WN2 orbits the sun every 4,350 days (11.91 years), coming as close as 4.70 AU and reaching as far as 5.73 AU from the sun. 2000 WN2 is about 33.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of New York.

The rotation of 2000 WN2 has been observed. It completes a rotation on its axis every 7.37 hours.

No Close Approaches

2000 WN2's orbit is 3.76 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 WN2's orbit is determined by observations dating back to March 9, 1994. It was last officially observed on June 17, 2023. The IAU Minor Planet Center records 2,078 observations used to determine its orbit.

Accessibility and Exploration

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