Overview
2015 DN215 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 DN215 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 DN215 orbits the sun every 1,660 days (4.54 years), coming as close as 0.69 AU and reaching as far as 4.79 AU from the sun. Its orbit is highly elliptical. 2015 DN215 is about 0.5 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 2015 DN215 has been observed. It completes a rotation on its axis every 18.20 hours.
Close Approaches
2015 DN215's orbit is 0.02 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.
2015 DN215 has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| March 3, 2164 | 8,339,141 | 21.871 |
| March 3, 2173 | 8,577,444 | 21.907 |
