Overview

65679 (1989 UQ) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1989 UQ as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1989 UQ orbits the sun every 320 days (0.88 years), coming as close as 0.67 AU and reaching as far as 1.16 AU from the sun. 1989 UQ is about 0.9 kilometers in diameter, making it a small to average asteroid, comparable in size to the Golden Gate Bridge.

The rotation of 1989 UQ has been observed. It completes a rotation on its axis every 7.75 days.

1989 UQ's spectral type (Tholen) / B (SMASSII) indicates that it is likely to contain iron, hydrogen, ammonia, and nitrogen.

Close Approaches

1989 UQ's orbit is 0.01 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.

1989 UQ has 25 close approaches predicted in the coming decades:

Images and Observations

1989 UQ's orbit is determined by observations dating back to Nov. 20, 1954. It was last officially observed on Nov. 23, 2017. The IAU Minor Planet Center records 725 observations used to determine its orbit.

Accessibility and Exploration

1989 UQ can be reached with a journey of 434 days. This trajectory would require a delta-v of 8.718 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 99,746 potential trajectories and launch windows to this asteroid.
