Tsia

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the city of Cleveland, Ohio (13.33 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Tsia orbits the sun every 1,620 days (4.44 years), coming as close as 2.18 AU and reaching as far as 3.22 AU from the sun. Tsia is about 13.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Cleveland, Ohio.

The rotation of Tsia has been observed. It completes a rotation on its axis every 12.59 hours.

No Close Approaches

Tsia's orbit is 1.17 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

Tsia's orbit is determined by observations dating back to May 18, 1936. It was last officially observed on March 6, 2023. The IAU Minor Planet Center records 4,533 observations used to determine its orbit.
