Key Facts


Asplinda is a large asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified Asplinda as potentially hazardous because its orbit does not bring it close to Earth.

Asplinda orbits the sun every 2,910 days (7.97 years), coming as close as 3.26 AU and reaching as far as 4.72 AU from the sun. Asplinda is about 45.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Asplinda has been observed. It completes a rotation on its axis every 16.54 hours.

No Close Approaches

Asplinda's orbit is 2.28 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.

Images and Observations

Asplinda's orbit is determined by observations dating back to Sept. 28, 1921. It was last officially observed on Oct. 2, 2021. The IAU Minor Planet Center records 2,871 observations used to determine its orbit.

Scientists have been able to determine this object's shape.
