Alekhin is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Alekhin as potentially hazardous because its orbit does not bring it close to Earth.
Alekhin orbits the sun every 1,380 days (3.78 years), coming as close as 1.87 AU and reaching as far as 2.97 AU from the sun. Alekhin is about 18.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.
The rotation of Alekhin has been observed. It completes a rotation on its axis every 148.60 hours.
Alekhin's orbit is 0.86 AU from Earth's orbit at its closest point. This means that there is a very 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.
Alekhin's orbit is determined by observations dating back to April 14, 1926. It was last officially observed on April 1, 2023. The IAU Minor Planet Center records 4,530 observations used to determine its orbit.
