Detailed explanation-1: -Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
Detailed explanation-2: -The Sun was born about 4.6 billion years ago from the gravitational collapse of a vast cloud of gas and dust. Material in the center of the cloud was squeezed so tightly that it became hot enough to ignite nuclear fusion. Today, the Sun continues to fuse hydrogen atoms to make helium in its core.
Detailed explanation-3: -The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen(about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.
