111P/Helin-Roman-Crockett is a small comet whose orbit brings it closer to the sun than Jupiter. NASA JPL has not classified 111P/Helin-Roman-Crockett as potentially hazardous because its orbit does not bring it close to Earth.
111P/Helin-Roman-Crockett orbits the sun every 3,100 days (8.49 years), coming as close as 3.70 AU and reaching as far as 4.62 AU from the sun. 111P/Helin-Roman-Crockett is about 1.2 kilometers in diameter, making it larger than most asteroids, comparable in size to the U.S. Pentagon.
111P/Helin-Roman-Crockett's orbit is 2.72 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.
111P/Helin-Roman-Crockett's orbit is determined by observations dating back to Jan. 3, 1989. It was last officially observed on Dec. 21, 2012. The IAU Minor Planet Center records 137 observations used to determine its orbit.
