Sense: adjective/1
All four words describe someone or something that many people know about. Famous is the most general and common word — it can apply to anyone or anything widely known, from film stars to local landmarks. Renowned is more formal and carries a strong sense of respect; a renowned scientist is admired within their field. Notable is weaker — it simply means worth noticing or remembering, without implying widespread fame; a notable achievement may only be known to experts. Celebrated suggests public praise and recognition, especially in the arts; a celebrated painter is one whose work is shown and admired. For everyday use, famous is the safest choice. For a scientist or expert, renowned fits better. For an achievement or feature, notable works well.

Etymology
Well-known is formed by joining the adverb well (meaning 'thoroughly, fully, or to a great degree') with the past participle known (from the verb know). The compound has been in use since around the 14th century, originally meaning 'thoroughly known' and later expanding to 'known by many people.'
