Key Facts

Overview

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

Inarradas orbits the sun every 1,940 days (5.31 years), coming as close as 2.43 AU and reaching as far as 3.66 AU from the sun. Inarradas is about 25.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

The rotation of Inarradas has been observed. It completes a rotation on its axis every 24.82 hours.

No Close Approaches

Inarradas's orbit is 1.42 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

Inarradas's orbit is determined by observations dating back to Sept. 7, 1942. It was last officially observed on Feb. 19, 2023. The IAU Minor Planet Center records 3,126 observations used to determine its orbit.

Accessibility and Exploration

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