39803 (1997 UY15) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1997 UY15 as potentially hazardous because its orbit does not bring it close to Earth.
1997 UY15 orbits the sun every 4,450 days (12.18 years), coming as close as 4.90 AU and reaching as far as 5.68 AU from the sun. 1997 UY15 is about 14.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.
1997 UY15's orbit is 3.91 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.
1997 UY15's orbit is determined by observations dating back to Sept. 27, 1960. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 908 observations used to determine its orbit.
