545361 (2011 GZ61) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2011 GZ61 as potentially hazardous because its orbit does not bring it close to Earth.
2011 GZ61 orbits the sun every 102,000 days (279.26 years), coming as close as 37.91 AU and reaching as far as 47.35 AU from the sun. Based on its brightness and the way it reflects light, 2011 GZ61 is probably between 177.237 to 396.315 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.
2011 GZ61's orbit is 36.90 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 GZ61's orbit is determined by observations dating back to April 3, 2011. It was last officially observed on May 15, 2020. The IAU Minor Planet Center records 121 observations used to determine its orbit.
