Key Facts

Overview

Belisana is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Belisana as potentially hazardous because its orbit does not bring it close to Earth.

Belisana orbits the sun every 1,410 days (3.86 years), coming as close as 2.36 AU and reaching as far as 2.57 AU from the sun. Belisana is about 35.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Los Angeles.

The rotation of Belisana has been observed. It completes a rotation on its axis every 12.32 hours.

Belisana's spectral type S (Tholen) / S (SMASSII) indicates that it is likely to contain and .

No Close Approaches

Belisana's orbit is 1.34 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

Belisana's orbit is determined by observations dating back to Dec. 11, 1885. It was last officially observed on May 3, 2021. The IAU Minor Planet Center records 3,461 observations used to determine its orbit.

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