Overview
Dryope is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified Dryope as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
Dryope orbits the sun every 1,220 days (3.34 years), coming as close as 0.95 AU and reaching as far as 3.52 AU from the sun. Based on its brightness and the way it reflects light, Dryope is probably between 0.841 to 1.879 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
Dryope'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.
Dryope has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 13, 2062 | 29,004,751 | 11.861 |
| July 21, 2072 | 9,329,263 | 15.118 |
| July 17, 2129 | 2,533,320 | 14.019 |
| July 16, 2186 | 1,348,431 | 13.965 |
| July 29, 2196 | 23,789,685 | 17.258 |
Images and Observations
Dryope's orbit is determined by observations dating back to Jan. 19, 2005. It was last officially observed on Nov. 24, 2022. The IAU Minor Planet Center records 288 observations used to determine its orbit.
