19725 (1999 WT4) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 WT4 as potentially hazardous because its orbit does not bring it close to Earth.
1999 WT4 orbits the sun every 4,250 days (11.64 years), coming as close as 4.76 AU and reaching as far as 5.51 AU from the sun. 1999 WT4 is about 31.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of New York.
The rotation of 1999 WT4 has been observed. It completes a rotation on its axis every 56.70 hours.
1999 WT4's orbit is 3.78 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.
1999 WT4's orbit is determined by observations dating back to May 19, 1979. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 2,546 observations used to determine its orbit.
