2011 SO32 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 SO32 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2011 SO32 orbits the sun every 827 days (2.26 years), coming as close as 0.90 AU and reaching as far as 2.55 AU from the sun. Based on its brightness and the way it reflects light, 2011 SO32 is probably between 0.153 to 0.342 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2011 SO32's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2011 SO32 has 8 close approaches predicted in the coming decades:
