2. The Sun
The sun is a star all plants revolve around. The sun is named after the sun god Apollo. The Greeks thought Apollo carried the sun across the sky is his chariot. But we know that the sun is not drawn by a chariot. The Greek astronomers also thought theplanets revolved around Earth. That was called the geocentric theory, but the heliocentric theory is that the planets revolve around the sun. Nicolaus Copernicus developed this theory. Without the sun Earth would be a dark and dreary place to live. Food and crops would spoil and humans would starve from hunger. This is why the sun is important to all mankind.
