“It was initially believed that the Earth was the center of our solar system and that the Sun, the Moon, and the planets (Mercury, Venus, Mars, and Jupiter) revolved around it. This theory is called the geocentric model (geo: Earth; centric: at the center). It was developed by Greek mathematician Ptolemy in the 2nd century, but it wasn’t widely accepted until the 16th century.”
