Overview
2014 CU13 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2014 CU13 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2014 CU13 orbits the sun every 1,150 days (3.15 years), coming as close as 0.70 AU and reaching as far as 3.60 AU from the sun. Based on its brightness and the way it reflects light, 2014 CU13 is probably between 0.111 to 0.248 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
The rotation of 2014 CU13 has been observed. It completes a rotation on its axis every 14.36 hours.
Close Approaches
2014 CU13's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2014 CU13 has 1 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 28, 2115 | 26,032,439 | 23.732 |
