Aigoual

Key Facts

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

Overview

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

Aigoual orbits the sun every 1,670 days (4.57 years), coming as close as 2.24 AU and reaching as far as 3.26 AU from the sun. Based on its brightness and the way it reflects light, Aigoual is probably between 3.931 to 8.791 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.

The rotation of Aigoual has been observed. It completes a rotation on its axis every 4.33 hours.

No Close Approaches

Aigoual's orbit is 1.24 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

Aigoual's orbit is determined by observations dating back to Oct. 28, 1978. It was last officially observed on June 20, 2023. The IAU Minor Planet Center records 2,098 observations used to determine its orbit.

Accessibility and Exploration

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