Overview
2002 AV is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2002 AV as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2002 AV orbits the sun every 1,420 days (3.89 years), coming as close as 0.85 AU and reaching as far as 4.10 AU from the sun. Based on its brightness and the way it reflects light, 2002 AV is probably between 0.176 to 0.393 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2002 AV's spectral type None (Tholen) / K (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.
Close Approaches
2002 AV'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.
2002 AV has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Oct. 14, 2036 | 16,256,031 | 11.042 |
| Nov. 18, 2148 | 6,786,977 | 8.047 |
Images and Observations
2002 AV's orbit is determined by observations dating back to Jan. 5, 2002. It was last officially observed on July 11, 2005. The IAU Minor Planet Center records 218 observations used to determine its orbit.
