Sarpedon is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Sarpedon as potentially hazardous because its orbit does not bring it close to Earth.
Sarpedon orbits the sun every 4,390 days (12.02 years), coming as close as 5.15 AU and reaching as far as 5.35 AU from the sun. Sarpedon is about 77.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.
The rotation of Sarpedon has been observed. It completes a rotation on its axis every 22.74 hours.
Sarpedon's orbit is 4.16 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.
Sarpedon's orbit is determined by observations dating back to Oct. 4, 1977. It was last officially observed on Aug. 6, 2021. The IAU Minor Planet Center records 2,793 observations used to determine its orbit.
