Simon Marius (latinized form of Simon Mayr; 10 January 1573 – 5 January 1625)[1] was a German astronomer. He was born in Gunzenhausen, near Nuremberg, but spent most of his life in the city of Ansbach. He is best known for being among the first observers of the four largest moons of Jupiter, and his publication of his discovery led to charges of plagiarism.
