19299 (1996 SZ4) is a relatively small asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 1996 SZ4 as potentially hazardous because its orbit does not bring it close to Earth.
1996 SZ4 orbits the sun every 90,100 days (246.68 years), coming as close as 29.35 AU and reaching as far as 49.33 AU from the sun. Based on its brightness and the way it reflects light, 1996 SZ4 is probably between 69.913 to 156.329 kilometers in diameter, making it larger than most asteroids, very roughly comparable in size to the U.S. state of Delaware.
1996 SZ4's orbit is 28.40 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.
1996 SZ4's orbit is determined by observations dating back to Sept. 16, 1996. It was last officially observed on Dec. 21, 2008. The IAU Minor Planet Center records 43 observations used to determine its orbit.
