Wikipedia:Notability/Esoteric subjects

An esoteric subject is a subject that is known to a select group of people rather than the population at large.

For example, an internationally or nationally famous person (such as a head of state), a country, a large animal found in the typical zoo, a basic color, or a classic piece of literature may be household names to all, and therefore, the articles on these have been long created, are viewed by many, and their existence is not disputed.

But for other more obscure subjects, such as a planet in a far away galaxy, a rare disease, an event from centuries ago, or a local interest, an overwhelming percentage of the population does not know of its existence, let alone any facts about it.
