Briefings

An international team led by Queen's University Belfast researchers identified a population of asteroids orbiting Neptune, resolving a 120-year mystery. This discovery marks the first confirmed Neptune Trojan family since 1906, when similar populations were found around Jupiter, Saturn, and Uranus. The team used advanced telescope observations to map the new asteroid families, providing a complete picture of Neptune's orbital dynamics.

Key points

• A team led by Queen's University Belfast researchers identified a population of asteroids orbiting Neptune, resolving a 120-year mystery.
• This discovery marks the first confirmed Neptune Trojan family since 1906, when similar populations were found around Jupiter, Saturn, and Uranus.

Context

Astronomers have long sought to understand Neptune's orbital dynamics, but the lack of a confirmed Neptune Trojan family has remained a significant gap in knowledge since the 1906 discovery of similar populations around Jupiter, Saturn, and Uranus.

Limitations

The evidence is limited to the 2026-11-03 article, which reports the team's successful identification of the new family. The specific number of asteroids, their precise orbital parameters, and the exact date of the initial discovery in 1906 are not provided in the source.
