Overview
2020 DR2 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 DR2 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2020 DR2 orbits the sun every 1,260 days (3.45 years), coming as close as 0.71 AU and reaching as far as 3.86 AU from the sun. Based on its brightness and the way it reflects light, 2020 DR2 is probably between 0.462 to 1.033 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2020 DR2's orbit is 0.01 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.
2020 DR2 has 7 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Sept. 2, 2033 | 19,535,401 | 24.092 |
| Sept. 22, 2064 | 24,458,227 | 16.933 |
