Asteroid 4615, Zinner, was discovered on September 13, 1923 by Karl Reinmuth at Heidelberg, Germany. It has a period of 4 years, 70 days.
It was named for distinguished German astronomer Ernst Zinner (1886-1970), who studied variable stars and researched the history of astronomy in the Middle Ages.
Its astrological meaning seems to come from what its name might suggest: "sinner".
The glyph for Zinner is mine.
