2016 GZ251 is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 2016 GZ251 as potentially hazardous because its orbit does not bring it close to Earth.
2016 GZ251 orbits the sun every 27,400 days (75.02 years), coming as close as 10.15 AU and reaching as far as 25.45 AU from the sun. Based on its brightness and the way it reflects light, 2016 GZ251 is probably between 16.016 to 35.813 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Indianapolis.
2016 GZ251's orbit is 9.30 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.
2016 GZ251's orbit is determined by observations dating back to March 13, 2011. It was last officially observed on May 17, 2017. The IAU Minor Planet Center records 59 observations used to determine its orbit.
