Key Facts

Overview

122460 (2000 QB146) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2000 QB146 as potentially hazardous because its orbit does not bring it close to Earth.

2000 QB146 orbits the sun every 4,360 days (11.94 years), coming as close as 4.81 AU and reaching as far as 5.64 AU from the sun. Based on its brightness and the way it reflects light, 2000 QB146 is probably between 9.967 to 22.286 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.

The rotation of 2000 QB146 has been observed. It completes a rotation on its axis every 55.08 hours.

No Close Approaches

2000 QB146's orbit is 3.84 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

2000 QB146's orbit is determined by observations dating back to Feb. 24, 1995. It was last officially observed on May 30, 2023. The IAU Minor Planet Center records 1,220 observations used to determine its orbit.

Accessibility and Exploration

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