Angelo Secchi also studied the Sun and was one of the first scientists to state that the Sun was a star. He observed solar eclipses, solar eruptions, and sun spot activity. Angelo Secchi discovered that stars can be categorized by the type of light they give off and created a system to organize the stars.
