Schaefer is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Schaefer as potentially hazardous because its orbit does not bring it close to Earth.
Schaefer orbits the sun every 2,060 days (5.64 years), coming as close as 2.53 AU and reaching as far as 3.80 AU from the sun. Schaefer is about 10.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
Schaefer's orbit is 1.54 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.
Schaefer's orbit is determined by observations dating back to Sept. 20, 1979. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 1,985 observations used to determine its orbit.
