Pianoro is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Pianoro as potentially hazardous because its orbit does not bring it close to Earth.
Pianoro orbits the sun every 1,930 days (5.28 years), coming as close as 2.70 AU and reaching as far as 3.37 AU from the sun. Pianoro is about 11.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Boston.
Pianoro's orbit is 1.81 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.
Pianoro's orbit is determined by observations dating back to Aug. 20, 1990. It was last officially observed on Dec. 22, 2022. The IAU Minor Planet Center records 3,768 observations used to determine its orbit.
