Key Facts

Overview

108516 (2001 KR75) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 2001 KR75 as potentially hazardous because its orbit does not bring it close to Earth.

2001 KR75 orbits the sun every 1,290 days (3.53 years), coming as close as 1.55 AU and reaching as far as 3.09 AU from the sun. 2001 KR75 is about 2.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 2001 KR75 has been observed. It completes a rotation on its axis every 6.68 hours.

No Close Approaches

2001 KR75's orbit is 0.68 AU from Earth's orbit at its closest point. This means that there is a very 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

2001 KR75's orbit is determined by observations dating back to Sept. 28, 1987. It was last officially observed on Dec. 24, 2022. The IAU Minor Planet Center records 1,547 observations used to determine its orbit.

Accessibility and Exploration

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