25856 (2000 EZ170) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 2000 EZ170 as potentially hazardous because its orbit does not bring it close to Earth.
2000 EZ170 orbits the sun every 2,360 days (6.46 years), coming as close as 3.15 AU and reaching as far as 3.79 AU from the sun. Based on its brightness and the way it reflects light, 2000 EZ170 is probably between 7.287 to 16.294 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
2000 EZ170's orbit is 2.17 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 EZ170's orbit is determined by observations dating back to Oct. 29, 1997. It was last officially observed on Aug. 3, 2021. The IAU Minor Planet Center records 1,575 observations used to determine its orbit.
