The proposed names should be of things, people, or places of long-standing cultural, historical, or geographical significance, worthy of being memorialized through naming of a celestial object. Although not necessary, the names may be drawn from themes related to the sky and astronomy, or related in some way to the constellation that the exoplanetary system lies in.
The two names should follow a common naming theme. The naming theme describing how the names are related in some logical way should be summarized in a sentence or two, and be broad enough that additional names could be drawn from the literature to name additional objects in that exoplanetary system in the future (e.g. additional planets which might be discovered, additional stellar companions). Example: Rivers of country XYZ. Fictional lands in 19th century stories from country XYZ, etc.
Proposed names (after translation) should be:
○ Between 4 and 16 characters (including spaces or punctuation)
○ Preferably one word.
○ Pronounceable (in some language).
○ Not identical to,or too similar to, an existing name of an astronomical object.
In addition, it is not allowed to propose:
○ Names of a commercial nature, protected by trademarks or intellectual property
○ Names of individuals, places or events known for political, military or religious activities.
○ Names of individuals that died less than a century ago (1919).
○ Names of living individuals.
○ Names of organization.
○ Contrived names (i.e. new, invented).
○ Names that include numbers or punctuation marks (diacritics are acceptable).
