The only one I knew in German is Jungfrau (Virgo). And it has come to my attention before that a lot of English speakers don't even know what the Latin names actually mean. And the reason why I know they are mispronounced in English is because my cousin told me the Latin pronunciation rules.
For example "cancer" in in Latin pronounced as "Kank - er"... Which is also how the disease is pronounced in many languages, but the name of the disease and the zodiac sign have the same origin, which is the reference to the animal crab. The first tumor spot was said to look like a crab, hence the name of the disease. (The logo of the Dutch foundation fighting cancer (Koningin Wilhelmina Fonds) is even a crab with a sword stabbed through it, which is quite symbolic, don't you think).
Although astrology is not officially recognized as a form of science (knowledge about space is called astronomy... one letter difference, but a complete different thing), I could understand Latin names could be used internationally (like they use latin names for organs in medical science and latin names for animals and plants in biology), but in the communication of speaking to the common folk this was a bit beyond me. I mean when speaking of my organs, I still say my heart and not of my cor meum. It always seemed a bit odd to me.
