Simon Marius

Simon Marius was a German astronomer who lived between 1573-1624. He made observations of the heavens using a telescope and published yearly astronomical tables.

Throughout most of his life, Marius was troubled with charges of copying data from other scientists. Although he named the four moons of Jupiter, their discovery is generally credited to Galileo.

Due to his strong religious beliefs, Marius never accepted the Copernican model of the universe.
