Key Facts

Overview

9557 (1986 QL2) is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1986 QL2 as potentially hazardous because its orbit does not bring it close to Earth.

1986 QL2 orbits the sun every 2,050 days (5.61 years), coming as close as 2.67 AU and reaching as far as 3.65 AU from the sun. 1986 QL2 is about 11.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of 1986 QL2 has been observed. It completes a rotation on its axis every 53.65 hours.

No Close Approaches

1986 QL2's orbit is 1.66 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

1986 QL2's orbit is determined by observations dating back to Aug. 28, 1986. It was last officially observed on April 23, 2023. The IAU Minor Planet Center records 3,096 observations used to determine its orbit.

Accessibility and Exploration

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