Comet C/2021 J2 (PANSTARRS) is an object whose orbit does not match any defined comet orbit class. NASA JPL has not classified PANSTARRS as potentially hazardous because its orbit does not bring it close to Earth.
PANSTARRS orbits the sun every 464,000 days (1,270.36 years), coming as close as 4.71 AU and reaching as far as 229.69 AU from the sun. Its orbit is highly elliptical.
PANSTARRS's orbit is 3.70 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.
PANSTARRS's orbit is determined by observations dating back to March 20, 2021. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 210 observations used to determine its orbit.
