Key Facts

Overview

11436 (1969 QR) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1969 QR as potentially hazardous because its orbit does not bring it close to Earth.

1969 QR orbits the sun every 1,210 days (3.31 years), coming as close as 1.91 AU and reaching as far as 2.54 AU from the sun. 1969 QR is about 3.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1969 QR has been observed. It completes a rotation on its axis every 2.65 hours.

No Close Approaches

1969 QR's orbit is 0.90 AU from Earth's orbit at its closest point. This means that there is a very 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

1969 QR's orbit is determined by observations dating back to Aug. 22, 1969. It was last officially observed on Feb. 3, 2023. The IAU Minor Planet Center records 2,655 observations used to determine its orbit.

Accessibility and Exploration

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