530664 (2011 SO277) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2011 SO277 as potentially hazardous because its orbit does not bring it close to Earth.
2011 SO277 orbits the sun every 61,200 days (167.56 years), coming as close as 30.22 AU and reaching as far as 30.54 AU from the sun. Based on its brightness and the way it reflects light, 2011 SO277 is probably between 74.568 to 166.740 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2011 SO277's orbit is 29.20 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2011 SO277's orbit is determined by observations dating back to Nov. 20, 2008. It was last officially observed on Sept. 22, 2022. The IAU Minor Planet Center records 105 observations used to determine its orbit.
