P/2011 S1 (Gibbs) is a large comet whose orbit is approximately between Jupiter and Neptune. NASA JPL has not classified Gibbs as potentially hazardous because its orbit does not bring it close to Earth.
Gibbs orbits the sun every 9,300 days (25.46 years), coming as close as 6.89 AU and reaching as far as 10.41 AU from the sun. Based on its brightness and the way it reflects light, Gibbs is probably between 2658.000 to 5943.469 kilometers in diameter, making it the largest asteroid/dwarf planet, very roughly comparable in size to the U.S. state of Alaska.
Gibbs's orbit is 5.90 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.
Gibbs's orbit is determined by observations dating back to Sept. 29, 2010. It was last officially observed on Jan. 3, 2016. The IAU Minor Planet Center records 145 observations used to determine its orbit.
