Overview
620084 (2014 WD201) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2014 WD201 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2014 WD201 orbits the sun every 1,110 days (3.04 years), coming as close as 1.04 AU and reaching as far as 3.15 AU from the sun. Based on its brightness and the way it reflects light, 2014 WD201 is probably between 0.350 to 0.784 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.
Close Approaches
2014 WD201's orbit is 0.04 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.
2014 WD201 has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| July 5, 2032 | 9,437,368 | 9.098 |
| Aug. 7, 2035 | 15,005,239 | 8.333 |
| July 2, 2141 | 13,377,023 | 10.080 |
| July 25, 2144 | 8,013,889 | 7.943 |
| Aug. 29, 2147 | 28,596,363 | 11.017 |
