Comet 389P/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 389P/Siding Spring as potentially hazardous because its orbit does not bring it close to Earth.
389P/Siding Spring orbits the sun every 4,870 days (13.33 years), coming as close as 1.66 AU and reaching as far as 9.58 AU from the sun. Its orbit is highly elliptical.
389P/Siding Spring's orbit is 0.77 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.
389P/Siding Spring's orbit is determined by observations dating back to Sept. 1, 2006. It was last officially observed on Nov. 15, 2019. The IAU Minor Planet Center records 103 observations used to determine its orbit.
