sidosorbita

Sidosorbita is a term used primarily in speculative discourse and science fiction to refer to a class of orbital configurations described as stable or quasi-stable orbits around a planet or moon. The term is not part of standard celestial mechanics and has no formal definition in peer-reviewed astrodynamics; it is used informally to discuss ideas about how a small body could persist in an unusual orbital regime amid perturbations such as atmospheric drag, tidal forces, and magnetic interactions.

In these usages, a sidosorbita would involve a balance of forces: gravitational attraction toward the primary, centrifugal effects in the rotating frame, drag from upper atmospheric or exospheric particles, radiation pressure, and, where relevant, magnetic or plasma interactions with the planet's magnetosphere. Variants describe near-equatorial, elliptical, or resonant orbits that exploit planetary rotation or magnetic fields to reduce decay.

The concept is mainly employed as a hypothetical construct to explore orbital longevity and energy economics in fictional or speculative settings, rather than as a proven mechanism. In literature and media, sidosorbita may serve as a plot device for long-lived satellites, resource harvesting, or exomoon studies, without implying real-world applicability.
