Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Indianapolis (28.25 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Apisaon orbits the sun every 4,440 days (12.16 years), coming as close as 4.88 AU and reaching as far as 5.69 AU from the sun. Apisaon is about 28.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

Apisaon's orbit is 3.88 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

Apisaon's orbit is determined by observations dating back to Nov. 16, 1976. It was last officially observed on Nov. 24, 2022. The IAU Minor Planet Center records 1,655 observations used to determine its orbit.

Accessibility and Exploration

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