Key Facts

  • Categorized as a Aten-class Asteroid
  • Comparable in size to the Golden Gate Bridge (0.57 km diameter)
  • Classified as a Near Earth Asteroid (NEA)
  • Not a Potentially Hazardous Object
  • See orbit simulation


87309 (2000 QP) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 QP 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 QP orbits the sun every 285 days (0.78 years), coming as close as 0.45 AU and reaching as far as 1.24 AU from the sun. 2000 QP is about 0.6 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 2000 QP has been observed. It completes a rotation on its axis every 2.17 hours.

No Close Approaches

2000 QP's orbit is 0.20 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

2000 QP's orbit is determined by observations dating back to July 8, 1975. It was last officially observed on Sept. 4, 2021. The IAU Minor Planet Center records 760 observations used to determine its orbit.

Accessibility and Exploration

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