Adelinda is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Adelinda as potentially hazardous because its orbit does not bring it close to Earth.
Adelinda orbits the sun every 2,310 days (6.32 years), coming as close as 2.95 AU and reaching as far as 3.89 AU from the sun. Adelinda is about 105.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Delaware.
The rotation of Adelinda has been observed. It completes a rotation on its axis every 6.60 hours.
Adelinda's orbit is 1.94 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.
Adelinda's orbit is determined by observations dating back to Jan. 19, 1885. It was last officially observed on Nov. 7, 2022. The IAU Minor Planet Center records 4,154 observations used to determine its orbit.
