Cyllarus is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Cyllarus as potentially hazardous because its orbit does not bring it close to Earth.
Cyllarus orbits the sun every 48,700 days (133.33 years), coming as close as 16.14 AU and reaching as far as 36.04 AU from the sun. Based on its brightness and the way it reflects light, Cyllarus is probably between 46.191 to 103.286 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Rhode Island.
Cyllarus's orbit is 15.20 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.
Cyllarus's orbit is determined by observations dating back to Oct. 12, 1998. It was last officially observed on Jan. 23, 2020. The IAU Minor Planet Center records 84 observations used to determine its orbit.
