45739 (2000 HR25) is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2000 HR25 as potentially hazardous because its orbit does not bring it close to Earth.
2000 HR25 orbits the sun every 2,920 days (7.99 years), coming as close as 2.72 AU and reaching as far as 5.27 AU from the sun. 2000 HR25 is about 15.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of 2000 HR25 has been observed. It completes a rotation on its axis every 24.11 hours.
2000 HR25's orbit is 1.72 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.
2000 HR25's orbit is determined by observations dating back to Oct. 6, 1931. It was last officially observed on June 13, 2023. The IAU Minor Planet Center records 3,395 observations used to determine its orbit.
