Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Indianapolis (24.64 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Balios orbits the sun every 4,270 days (11.69 years), coming as close as 4.42 AU and reaching as far as 5.89 AU from the sun. Balios is about 24.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Indianapolis.

No Close Approaches

Balios's orbit is 3.42 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

Balios's orbit is determined by observations dating back to Dec. 8, 1989. It was last officially observed on April 16, 2023. The IAU Minor Planet Center records 2,133 observations used to determine its orbit.

Accessibility and Exploration

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