13783 (1998 UJ20) is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 1998 UJ20 as potentially hazardous because its orbit does not bring it close to Earth.
1998 UJ20 orbits the sun every 1,380 days (3.78 years), coming as close as 1.91 AU and reaching as far as 2.94 AU from the sun. 1998 UJ20 is about 3.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
The rotation of 1998 UJ20 has been observed. It completes a rotation on its axis every 5.27 hours.
1998 UJ20's orbit is 0.91 AU from Earth's orbit at its closest point. This means that there is a very 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.
1998 UJ20's orbit is determined by observations dating back to Sept. 14, 1979. It was last officially observed on May 24, 2023. The IAU Minor Planet Center records 2,174 observations used to determine its orbit.
