6P/d'Arrest is a mid-sized comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 6P/d'Arrest as potentially hazardous because its orbit does not bring it close to Earth.
6P/d'Arrest orbits the sun every 2,400 days (6.57 years), coming as close as 1.36 AU and reaching as far as 5.65 AU from the sun. 6P/d'Arrest is about 3.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.
6P/d'Arrest's orbit is 0.35 AU from Earth's orbit at its closest point. This means that there is an 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.
6P/d'Arrest's orbit is determined by observations dating back to March 31, 1987. It was last officially observed on Jan. 14, 2016. The IAU Minor Planet Center records 2,194 observations used to determine its orbit.
