In total, there are 549 celebrities in the database being an Cancer star sign. To make it easier for you to find the actor, actress or other public figure the links to the respective birth horoscopes are split in chunks. They are sorted alphabetically by the first two letters of the surname.
Not only the respective Ascendant but the other planets, houses and aspects of the respective celebrity birth chart make the difference. In short, there are a multitude of sign combinations making it nearly impossible for somebody to have the exact same birth disposition, unless of course, they are identical twins.
This is the reason why newspaper horoscopes for the Cancer can never be right, unless it's a dominant Cancer. For that to be true many aspects or planets pointing towards the 4th house, the house of feelings & caring, and/or many planets in Cancer must be a given. Since the Moon is the Cancer's ruler, its position plays a significant part in any Cancer' birth chart, too.
Have a look for yourself.
