Key Facts

Overview

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

Ankara orbits the sun every 1,620 days (4.44 years), coming as close as 2.27 AU and reaching as far as 3.12 AU from the sun. Ankara is about 17.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

The rotation of Ankara has been observed. It completes a rotation on its axis every 35.54 hours.

No Close Approaches

Ankara's orbit is 1.26 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

Ankara's orbit is determined by observations dating back to Sept. 16, 1933. It was last officially observed on March 18, 2023. The IAU Minor Planet Center records 4,466 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
