444025 (2004 HJ79) is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2004 HJ79 as potentially hazardous because its orbit does not bring it close to Earth.
2004 HJ79 orbits the sun every 106,000 days (290.21 years), coming as close as 41.62 AU and reaching as far as 45.86 AU from the sun. Based on its brightness and the way it reflects light, 2004 HJ79 is probably between 97.399 to 217.791 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Connecticut.
The rotation of 2004 HJ79 has been observed. It completes a rotation on its axis every 7.50 hours.
2004 HJ79's orbit is 40.60 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.
2004 HJ79's orbit is determined by observations dating back to April 26, 2004. It was last officially observed on Feb. 23, 2017. The IAU Minor Planet Center records 74 observations used to determine its orbit.
