2017 DS109 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 DS109 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.
2017 DS109 orbits the sun every 1,110 days (3.04 years), coming as close as 0.91 AU and reaching as far as 3.28 AU from the sun. Based on its brightness and the way it reflects light, 2017 DS109 is probably between 0.016 to 0.037 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2017 DS109's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
2017 DS109 has 3 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 16, 2020 | 15,243,964 | 9.487 |
| May 27, 2023 | 10,382,164 | 10.755 |
| June 15, 2026 | 25,974,293 | 15.867 |
2017 DS109's orbit is determined by observations dating back to Feb. 14, 2017. It was last officially observed on March 5, 2017. The IAU Minor Planet Center records 148 observations used to determine its orbit.
