Have you noticed that some of the days of the week have the name of some planets / stars?

For example: 1. Sunday = day of the Sun (as it was called by the Roman Empire) 2. Monday = day of the Moon (as it was called by the Roman Empire) 3. Saturday = day of Saturn (as it was called by the Roman Emnpire). However, the rest of the week days in the English language don't seem to have the name of the planets but now that I mentioned this issue, I would also like to explain the meaning of the days in the Romanian language too. 1. Sunday (English) = Duminica (Romanian). If I were to translate the word Duminica in English I would say it means "the day of the Lord" which is how Christians named the first day of the week when Jesus has risen; 2. Monday (English) = Luni (Romanian); and the word "luni" means "moons" if I were to translate it in English 3. Tuesday (English) = Marti (Romanian); the word "Marti" means "Mars" (the planet) 4. Wednesday (English) = Miercuri (Romanian); the word "Miercuri" most likely means "Mercury" (the planet) 5. Thursday (English) = Joi (Romanian); I can't associate the word "Joi" with anything 6. Friday (English) = Vineri (Romanian); the word "Vineri" most likely means "Venus" (the planet) 7. Saturday (English) = Sambata (Romanian); the word "Sambata" most likely means "rest" and it comes from an old Jewish word "Shabat" or "Sabbath" as Americans and English people are familiar with. How about in your language? Do the days of the week have any meaning? Do they have the names of some planets? If I got anything wrong please let me know.
