Hylonome is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Hylonome as potentially hazardous because its orbit does not bring it close to Earth.
Hylonome orbits the sun every 46,000 days (125.94 years), coming as close as 18.99 AU and reaching as far as 31.25 AU from the sun. Based on its brightness and the way it reflects light, Hylonome is probably between 50.647 to 113.250 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
Hylonome's orbit is 18.00 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.
Hylonome's orbit is determined by observations dating back to March 9, 1995. It was last officially observed on June 14, 2010. The IAU Minor Planet Center records 78 observations used to determine its orbit.
