Comet P/2006 HR30 (Siding Spring) is an object with a medium-length orbit that is highly inclined to the ecliptic plane of the solar system. NASA JPL has classified Siding Spring as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.
Siding Spring orbits the sun every 7,980 days (21.85 years), coming as close as 1.23 AU and reaching as far as 14.41 AU from the sun. Its orbit is highly elliptical.
The rotation of Siding Spring has been observed. It completes a rotation on its axis every 70.70 hours.
Siding Spring's orbit is 0.45 AU from Earth's orbit at its closest point. This means that there is a 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 July 6, 2005. It was last officially observed on May 5, 2008. The IAU Minor Planet Center records 3,059 observations used to determine its orbit.
