Key Facts

Overview

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

Hanna orbits the sun every 1,720 days (4.71 years), coming as close as 2.20 AU and reaching as far as 3.42 AU from the sun. Hanna is about 24.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

Hanna's orbit is 1.19 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

Hanna's orbit is determined by observations dating back to July 24, 1933. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 3,770 observations used to determine its orbit.

Accessibility and Exploration

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