612658 (2003 TH58) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 TH58 as potentially hazardous because its orbit does not bring it close to Earth.
2003 TH58 orbits the sun every 90,600 days (248.05 years), coming as close as 35.74 AU and reaching as far as 43.20 AU from the sun. Based on its brightness and the way it reflects light, 2003 TH58 is probably between 93.876 to 209.913 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.
2003 TH58's orbit is 34.80 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.
2003 TH58's orbit is determined by observations dating back to Dec. 31, 2002. It was last officially observed on Dec. 9, 2020. The IAU Minor Planet Center records 40 observations used to determine its orbit.
