The Sun is a huge ball of incandescent plasma at the center of our Solar System. It accounts for more than 99.86% of the mass of the Solar System, and provides all the energy we need for life here on Earth. Ancient civilizations, such as the Romans worshiped the Sun because they saw it as something that brought life. It was given various names such as Sol by the Romans and Helios by the Greeks. And perhaps that worship was reasonable, for without the Sun, life on Earth just wouldn’t be possible.
