Overview

2016 UO5 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2016 UO5 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.

2016 UO5 orbits the sun every 311 days (0.85 years), coming as close as 0.72 AU and reaching as far as 1.08 AU from the sun. Based on its brightness and the way it reflects light, 2016 UO5 is probably between 0.012 to 0.054 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2016 UO5's orbit is 0.07 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.

2016 UO5 has 3 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Dec. 9, 2022 17,653,149 7.716
Sept. 12, 2033 20,713,385 8.988
Dec. 10, 2051 19,008,519 8.051

Images and Observations

2016 UO5's orbit is determined by observations dating back to Oct. 20, 2016. It was last officially observed on Nov. 5, 2016. The IAU Minor Planet Center records 32 observations used to determine its orbit.

Accessibility and Exploration

2016 UO5 can be reached with a journey of 362 days. This trajectory would require a delta-v of 9.233 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 48,748 potential trajectories and launch windows to this asteroid.
