138727 (2000 SU180) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 SU180 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 SU180 orbits the sun every 1,120 days (3.07 years), coming as close as 0.83 AU and reaching as far as 3.38 AU from the sun. Based on its brightness and the way it reflects light, 2000 SU180 is probably between 0.360 to 0.805 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.
2000 SU180'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 SU180 has 4 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
Feb. 6, 2059 | 17,464,008 | 12.317 |
Jan. 10, 2114 | 29,764,812 | 12.625 |
March 3, 2117 | 10,703,885 | 16.101 |
March 2, 2169 | 10,060,513 | 15.813 |
2000 SU180's orbit is determined by observations dating back to Sept. 27, 2000. It was last officially observed on Sept. 13, 2021. The IAU Minor Planet Center records 180 observations used to determine its orbit.
