Celuta

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the U.S. state of Rhode Island (49.99 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Celuta orbits the sun every 1,330 days (3.64 years), coming as close as 2.01 AU and reaching as far as 2.72 AU from the sun. Celuta is about 50.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Rhode Island.

The rotation of Celuta has been observed. It completes a rotation on its axis every 19.84 hours.

Celuta's spectral type S (Tholen) / K (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Celuta's orbit is 1.02 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

Celuta's orbit is determined by observations dating back to Dec. 7, 1883. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 6,861 observations used to determine its orbit.
