Key Facts

Overview

7467 (1989 WQ1) is a mid-sized asteroid with an orbit that crosses the orbit of Mars. NASA JPL has not classified 1989 WQ1 as potentially hazardous because its orbit does not bring it close to Earth.

1989 WQ1 orbits the sun every 777 days (2.13 years), coming as close as 1.44 AU and reaching as far as 1.86 AU from the sun. Based on its brightness and the way it reflects light, 1989 WQ1 is probably between 1.926 to 4.306 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

The rotation of 1989 WQ1 has been observed. It completes a rotation on its axis every 7.63 days.

No Close Approaches

1989 WQ1's orbit is 0.49 AU from Earth's orbit at its closest point. This means that there is an 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

1989 WQ1's orbit is determined by observations dating back to Aug. 9, 1978. It was last officially observed on June 16, 2020. The IAU Minor Planet Center records 1,960 observations used to determine its orbit.

Accessibility and Exploration

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