A Trans-Neptunian Object is a small worldlet or planetoid lying within the Remote System.

  • They may be referred to as Remote System Objects (RSOs).

Description (Specifications)[edit]

A planet is considered to be a world within a system that has cleared its orbital position of worldlets, planetoids and other debris. Trans-Neptunian objects (commonly referred to as TNOs) lie within the outer part of a system where this process either hasn't occurred or is still ongoing.

Trans-Neptunian Objects typically lie within the Heliopause, the broad region where the star's Heliosphere becomes the Interstellar Medium.

The Terra System[edit]

Within the Terra system, a TNO is any minor planet that orbits Sol at a greater average distance than Neptune, which has a semi-major axis of 30.1 AU.

TNOs fall within two broad zones:

  1. Bodies having an orbital resonance with Neptune. These are generally referred to as Kuiper Main Belt objects.
  2. Scattered disc and detached objects.

Other Star Systems[edit]

Within the broader canvas of Charted Space, a TNO/RSO is considered to be any minor planet lying beyond the orbit of the outermost gas giant world or major planet within a system.

History & Background (Dossier)[edit]

The first trans-Neptunian object to be discovered in the Terra system was Pluto, around the year -2590.
