Comet P/2012 US27 (Siding Spring) is an object whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified Siding Spring as potentially hazardous because its orbit does not bring it close to Earth.
Siding Spring orbits the sun every 4,310 days (11.80 years), coming as close as 1.82 AU and reaching as far as 8.54 AU from the sun.
Siding Spring's orbit is 0.83 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.
Siding Spring's orbit is determined by observations dating back to Oct. 17, 2012. It was last officially observed on April 18, 2013. The IAU Minor Planet Center records 299 observations used to determine its orbit.
