What constellation was born on July 16 in 85 Gregorian calendar?

The constellation has nothing to do with the year, but only with the number of days in the solar calendar.

Cancer: June 21-July 22 in the solar calendar.

On a spring night, Cancer appears in a constellation slightly south. This symbol is represented by the claws of crabs. The guardian star of Cancer is the moon, and the patron saint is Diana, the goddess who dominates her mother.

Cancer's character can be expressed in one sentence: full of maternal love. Rich in feelings and sensitive to things. I am friendly and humble to the outside world, and I know the public quite well, but I have a strong defensive instinct at home and don't want my private life to be disturbed.
