Key Facts

Overview

87311 (2000 QJ1) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 QJ1 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 QJ1 orbits the sun every 733 days (2.01 years), coming as close as 0.78 AU and reaching as far as 2.40 AU from the sun. 2000 QJ1 is about 1.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

2000 QJ1's orbit is 0.11 AU from Earth's orbit at its closest point. This means that there is a 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 QJ1's orbit is determined by observations dating back to Aug. 16, 1982. It was last officially observed on Oct. 17, 2022. The IAU Minor Planet Center records 1,857 observations used to determine its orbit.

Accessibility and Exploration

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