2021 DG17 is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2021 DG17 as potentially hazardous because its orbit does not bring it close to Earth.
2021 DG17 orbits the sun every 178,000 days (487.34 years), coming as close as 47.55 AU and reaching as far as 76.35 AU from the sun. Based on its brightness and the way it reflects light, 2021 DG17 is probably between 262.153 to 586.192 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of Virginia.
2021 DG17's orbit is 46.60 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.
2021 DG17's orbit is determined by observations dating back to March 12, 2005. It was last officially observed on April 8, 2022. The IAU Minor Planet Center records 17 observations used to determine its orbit.
