Overview
430440 (2000 OH) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 OH as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 OH orbits the sun every 1,380 days (3.78 years), coming as close as 0.99 AU and reaching as far as 3.86 AU from the sun. Based on its brightness and the way it reflects light, 2000 OH is probably between 0.788 to 1.762 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2000 OH's orbit is 0.03 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.
2000 OH has 5 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 28, 2094 | 8,347,463 | 13.759 |
| July 7, 2109 | 6,821,735 | 14.194 |
| July 15, 2169 | 10,986,770 | 14.272 |
| July 9, 2184 | 7,720,945 | 14.251 |
| June 14, 2199 | 22,739,717 | 15.319 |
Images and Observations
2000 OH's orbit is determined by observations dating back to July 21, 2000. It was last officially observed on Dec. 31, 2019. The IAU Minor Planet Center records 372 observations used to determine its orbit.
