centrimera

Centrimera is a hypothetical celestial object that has been proposed as a potential explanation for certain observed astronomical phenomena. The concept of a centrimera is derived from a combination of "centaur" and "mera," suggesting an object that shares characteristics of both. Specifically, a centrimera is envisioned as a large, icy body in the outer solar system, similar to a centaur, but with a more pronounced and extended coma or atmosphere, akin to a comet.

The primary characteristic differentiating a centrimera from a standard centaur would be its enhanced activity. While centaurs typically exhibit transient cometary activity, a centrimera would possess a more persistent and substantial volatile-rich atmosphere. This sustained activity could lead to an apparent brightness that might be mistaken for other types of celestial bodies, or it could contribute to observed dust trails in the outer solar system.

The theoretical basis for centrimeras arises from the need to account for certain orbits and brightness variations observed among trans-Neptunian objects. Some researchers suggest that if such objects were to undergo a significant release of volatiles, their appearance and orbital dynamics could be altered in ways that align with the centrimera model. However, it is important to note that centrimera remains a theoretical construct, and no definitive observational evidence has yet confirmed the existence of such objects. Further research and observations are required to ascertain whether centrimeras are a real component of our solar system or simply a theoretical concept.
