Overview

531944 (2013 CU83) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2013 CU83 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2013 CU83 orbits the sun every 532 days (1.46 years), coming as close as 1.05 AU and reaching as far as 1.52 AU from the sun. Based on its brightness and the way it reflects light, 2013 CU83 is probably between 0.094 to 0.422 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2013 CU83's orbit is 0.04 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.

2013 CU83 has 8 close approaches predicted in the coming decades:

Images and Observations

2013 CU83's orbit is determined by observations dating back to Feb. 10, 2013. It was last officially observed on Nov. 26, 2022. The IAU Minor Planet Center records 335 observations used to determine its orbit.

Accessibility and Exploration

2013 CU83 can be reached with a journey of 354 days. This trajectory would require a delta-v of 10.593 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 374 potential trajectories and launch windows to this asteroid.
