How it's used

Scientific terms like this are often borrowed directly from written Chinese and pronounced with Cantonese readings. While it is a standard astronomical term, it is rarely used in casual daily conversation unless discussing science or astrology. In modern internet slang, the term 海王 is frequently used to describe a person who flirts with many people simultaneously, which is completely unrelated to the planet.

Common mistake

Do not confuse the literal planet name with the slang term 海王, which refers to a player or serial flirt. Using the full name 海王星 usually avoids this confusion, but context is key.
