Why Does the Sun Shine?

The sun is a mass of incandescent gas
 A gigantic nuclear furnace
 Where hydrogen is built into helium
 At a temperature of millions of degrees
 Yo-ho, it's hot, the sun is not
 A place where we could live
 But here on Earth, there'd be no life
 Without the light it gives
 We need its light, we need its heat
 We need its energy
 Without the sun, without a doubt
 There'd be no you and me
 The sun is a mass of incandescent gas
 A gigantic nuclear furnace
 Where hydrogen is built into helium
 At a temperature of millions of degrees
 The sun is hot
 The sun is so hot
 That everything on it is a gas
 Copper, iron, aluminum, on the surface of the sun are all gas
 The sun is large
 The sun is so large
 A million Earths could fit inside
 And yet, the sun's just a middle-sized star
 The sun is far away
 It's about ninety-three million miles away
 And that's why it looks so small
 But even when it's out of sight
 It shines both night and day
 The sun gives light, the sun gives heat
 The sunlight that we see
 The sunlight comes from our own sun's atomic energy
 Scientists have found that the sun is a huge atom-crushing machine
 The heat and light from the sun are caused by the nuclear reaction
 Between hydrogen, carbon, nitrogen, and helium
 The sun is a mass of incandescent gas
 A gigantic nuclear furnace
 Where hydrogen is built into helium
 At a temperature of millions of degrees
