Bella

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the U.S. state of Rhode Island (40.62 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Bella orbits the sun every 1,480 days (4.05 years), coming as close as 2.13 AU and reaching as far as 2.95 AU from the sun. Bella is about 40.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Bella has been observed. It completes a rotation on its axis every 14.22 hours.

No Close Approaches

Bella's orbit is 1.18 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

Bella's orbit is determined by observations dating back to Oct. 25, 1913. It was last officially observed on March 26, 2023. The IAU Minor Planet Center records 6,918 observations used to determine its orbit.
