84522 (2002 TC302) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2002 TC302 as potentially hazardous because its orbit does not bring it close to Earth.
2002 TC302 orbits the sun every 152,000 days (416.15 years), coming as close as 39.20 AU and reaching as far as 72.34 AU from the sun. Based on its brightness and the way it reflects light, 2002 TC302 is probably between 437.074 to 977.327 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Japan.
The rotation of 2002 TC302 has been observed. It completes a rotation on its axis every 56.10 hours.
2002 TC302's orbit is 38.40 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.
2002 TC302's orbit is determined by observations dating back to Aug. 5, 2000. It was last officially observed on Dec. 2, 2022. The IAU Minor Planet Center records 518 observations used to determine its orbit.
