Elephenor is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Elephenor as potentially hazardous because its orbit does not bring it close to Earth.
Elephenor orbits the sun every 4,380 days (11.99 years), coming as close as 4.92 AU and reaching as far as 5.56 AU from the sun. Based on its brightness and the way it reflects light, Elephenor is probably between 10.533 to 23.553 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.
Elephenor's orbit is 3.94 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.
Elephenor's orbit is determined by observations dating back to Nov. 8, 1951. It was last officially observed on Jan. 20, 2023. The IAU Minor Planet Center records 1,526 observations used to determine its orbit.
