Itha

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Indianapolis (21.56 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Itha orbits the sun every 1,770 days (4.85 years), coming as close as 2.32 AU and reaching as far as 3.41 AU from the sun. Itha is about 21.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Itha has been observed. It completes a rotation on its axis every 3.47 hours.

No Close Approaches

Itha's orbit is 1.32 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

Itha's orbit is determined by observations dating back to Aug. 23, 1919. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 4,005 observations used to determine its orbit.
