162979 (2001 RA12) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2001 RA12 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2001 RA12 orbits the sun every 1,060 days (2.90 years), coming as close as 0.93 AU and reaching as far as 3.14 AU from the sun. Based on its brightness and the way it reflects light, 2001 RA12 is probably between 0.576 to 1.288 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.
2001 RA12'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.
2001 RA12 has 3 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
Aug. 8, 2033 | 4,421,732 | 14.578 |
Aug. 19, 2068 | 23,559,010 | 17.310 |
July 12, 2138 | 24,095,658 | 12.958 |
2001 RA12's orbit is determined by observations dating back to Feb. 17, 2001. It was last officially observed on Jan. 16, 2018. The IAU Minor Planet Center records 147 observations used to determine its orbit.
