19308 (1996 TO66) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1996 TO66 as potentially hazardous because its orbit does not bring it close to Earth.
1996 TO66 orbits the sun every 103,838 days (284.29 years), coming as close as 37.96 AU and reaching as far as 48.51 AU from the sun. Based on its brightness and the way it reflects light, 1996 TO66 is probably between 291.444 to 651.688 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of Iowa.
The rotation of 1996 TO66 has been observed. It completes a rotation on its axis every 7.92 days.
1996 TO66's orbit is 37.04 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.
1996 TO66's orbit is determined by observations dating back to Oct. 1, 1983. It was last officially observed on Oct. 25, 2016. The IAU Minor Planet Center records 177 observations used to determine its orbit.
