Key Facts

Overview

184990 (2006 KE89) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2006 KE89 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2006 KE89 orbits the sun every 395 days (1.08 years), coming as close as 0.21 AU and reaching as far as 1.89 AU from the sun. Its orbit is highly elliptical. 2006 KE89 is about 2.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 2006 KE89 has been observed. It completes a rotation on its axis every 2.54 hours.

No Close Approaches

2006 KE89's orbit is 0.23 AU from Earth's orbit at its closest point. This means that there is a 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

2006 KE89's orbit is determined by observations dating back to June 6, 1994. It was last officially observed on July 6, 2023. The IAU Minor Planet Center records 2,073 observations used to determine its orbit.

Accessibility and Exploration

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