Key Facts

Overview

Laogonus is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified Laogonus as potentially hazardous because its orbit does not bring it close to Earth.

Laogonus orbits the sun every 4,280 days (11.72 years), coming as close as 5.00 AU and reaching as far as 5.32 AU from the sun. Based on its brightness and the way it reflects light, Laogonus is probably between 10.389 to 23.230 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Cleveland, Ohio.

No Close Approaches

Laogonus's orbit is 3.99 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

Laogonus's orbit is determined by observations dating back to Dec. 21, 1954. It was last officially observed on Aug. 31, 2022. The IAU Minor Planet Center records 1,586 observations used to determine its orbit.

Accessibility and Exploration

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