'For 2000 years ancient astronomers believed that the Earth was static and had other celestial bodies travelling in circular orbits around it. They believed this because of the apparent movement on the Sun and planets in relation to their viewpoint. In 1543, Copernicus published his Sun-centered model of the Solar System which put the Sun at the center of our solar system.'

Great description. FYI, our planet is 92,868,000 miles from our yellow dwarf star. If we were able to travel at the speed of light (186.000 mps) it takes 8 minutes for light from the sun to reach earth. Our earth, like the sun is over 4.3 billion years old, and it takes 23 hours, 56 minutes 4.07 seconds to rotate each day.
