Key Facts

  • Categorized as a Jupiter Trojan
  • Comparable in size to the city of Philadelphia (17.64 km diameter)
  • Not a Near Earth Object
  • Not a Potentially Hazardous Object
  • See orbit simulation

Overview

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

Lampos orbits the sun every 4,370 days (11.96 years), coming as close as 4.72 AU and reaching as far as 5.75 AU from the sun. Lampos is about 17.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Philadelphia.

No Close Approaches

Lampos's orbit is 3.74 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

Lampos's orbit is determined by observations dating back to March 25, 1971. It was last officially observed on June 30, 2023. The IAU Minor Planet Center records 898 observations used to determine its orbit.

Accessibility and Exploration

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