Overview
2013 OY3 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2013 OY3 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.
2013 OY3 orbits the sun every 279 days (0.76 years), coming as close as 0.55 AU and reaching as far as 1.12 AU from the sun. Based on its brightness and the way it reflects light, 2013 OY3 is probably between 0.019 to 0.085 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
Close Approaches
2013 OY3'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.
2013 OY3 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 7, 2023 | 18,761,845 | 12.067 |
| Sept. 8, 2026 | 16,552,974 | 6.709 |
| July 18, 2029 | 2,526,443 | 8.929 |
| Oct. 7, 2049 | 18,738,240 | 12.040 |
| July 20, 2107 | 21,024,306 | 12.794 |
Images and Observations
2013 OY3's orbit is determined by observations dating back to July 26, 2013. It was last officially observed on Aug. 4, 2013. The IAU Minor Planet Center records 42 observations used to determine its orbit.
Accessibility and Exploration
2013 OY3 can be reached with a journey of 330 days. This trajectory would require a delta-v of 10.124 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 7,893 potential trajectories and launch windows to this asteroid.
