15809 (1994 JS) is a relatively small asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1994 JS as potentially hazardous because its orbit does not bring it close to Earth.
1994 JS orbits the sun every 101,590 days (278.14 years), coming as close as 33.06 AU and reaching as far as 52.16 AU from the sun. Based on its brightness and the way it reflects light, 1994 JS is probably between 73.207 to 163.697 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. state of Delaware.
1994 JS's orbit is 32.07 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.
1994 JS's orbit is determined by observations dating back to April 6, 1995. It was last officially observed on June 12, 2001. The IAU Minor Planet Center records 38 observations used to determine its orbit.
