2013 TZ228 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2013 TZ228 as potentially hazardous because its orbit does not bring it close to Earth.
2013 TZ228 orbits the sun every 108,000 days (295.69 years), coming as close as 42.72 AU and reaching as far as 45.78 AU from the sun. Based on its brightness and the way it reflects light, 2013 TZ228 is probably between 84.053 to 187.949 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2013 TZ228's orbit is 41.70 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.
2013 TZ228's orbit is determined by observations dating back to Oct. 13, 2013. It was last officially observed on Oct. 29, 2022. The IAU Minor Planet Center records 11 observations used to determine its orbit.
