20739 (1999 XM193) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 XM193 as potentially hazardous because its orbit does not bring it close to Earth.
1999 XM193 orbits the sun every 4,340 days (11.88 years), coming as close as 4.49 AU and reaching as far as 5.93 AU from the sun. 1999 XM193 is about 27.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.
1999 XM193's orbit is 3.50 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 XM193's orbit is determined by observations dating back to March 2, 1990. It was last officially observed on April 1, 2023. The IAU Minor Planet Center records 1,431 observations used to determine its orbit.
