Huikilolani

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the U.S. Pentagon
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

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

Huikilolani orbits the sun every 1,170 days (3.20 years), coming as close as 1.82 AU and reaching as far as 2.52 AU from the sun. Based on its brightness and the way it reflects light, Huikilolani is probably between 1.001 to 2.239 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.

No Close Approaches

Huikilolani's orbit is 0.81 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

Huikilolani's orbit is determined by observations dating back to Oct. 12, 1982. It was last officially observed on June 19, 2023. The IAU Minor Planet Center records 522 observations used to determine its orbit.

Accessibility and Exploration

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