Key Facts

Overview

18173 (2000 QD8) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2000 QD8 as potentially hazardous because its orbit does not bring it close to Earth.

2000 QD8 orbits the sun every 1,320 days (3.61 years), coming as close as 1.87 AU and reaching as far as 2.83 AU from the sun. 2000 QD8 is about 2.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

2000 QD8's orbit is 0.86 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

2000 QD8's orbit is determined by observations dating back to March 26, 1992. It was last officially observed on Feb. 3, 2023. The IAU Minor Planet Center records 1,848 observations used to determine its orbit.

Accessibility and Exploration

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