15519 (1999 XW) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1999 XW as potentially hazardous because its orbit does not bring it close to Earth.
1999 XW orbits the sun every 2,110 days (5.78 years), coming as close as 2.88 AU and reaching as far as 3.56 AU from the sun. 1999 XW is about 16.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 1999 XW has been observed. It completes a rotation on its axis every 14.29 hours.
1999 XW's orbit is 1.90 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 XW's orbit is determined by observations dating back to April 22, 1950. It was last officially observed on April 22, 2023. The IAU Minor Planet Center records 2,617 observations used to determine its orbit.
