FUN SUN FACT:
Ancient cultures often modified natural rock formations or built stone monuments to mark the motions of the sun and moon, charting the seasons, creating calendars and monitoring eclipses.
Many believed the sun revolved around the Earth, with ancient Greek scholar Ptolemy formalising this “geocentric” model in 150 B.C.
Then, in 1543, Nicolaus Copernicus described a heliocentric, sun-centered model of the solar system, and in 1610, Galileo Galilei’s discovery of Jupiter’s moons revealed that not all heavenly bodies circled the Earth.
