Shajna

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the San Francisco Bay (9.45 km diameter)
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Shajna orbits the sun every 1,220 days (3.34 years), coming as close as 1.77 AU and reaching as far as 2.70 AU from the sun. Shajna is about 9.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of Shajna has been observed. It completes a rotation on its axis every 6.42 hours.

No Close Approaches

Shajna's orbit is 0.76 AU from Earth's orbit at its closest point. This means that there is a very 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

Shajna's orbit is determined by observations dating back to April 1, 1921. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 4,198 observations used to determine its orbit.
