Twinkle Twinkle Little Star
I know exactly what you are
Opaque ball of hot dense gas
Million times our planet's mass
Looking small because you're far
I know exactly what you are

Fusing atoms in your core
Hydrogen, helium, carbon and more
With such power you shine far
Twinkle twinkle little star
Bright when close and faint when far
I know exactly what you are

Smallest ones burn cool and slow
Still too hot to visit, though
Red stars dominate by far
Twinkle twinkle little star
Largest ones are hot and blue
Supernova when they're through

Then black hole or neutron star
I know exactly what you are
Forming from collapsing clouds
Cold and dusty gas enshrouds
Spinning, heating protostar
I know exactly what you are

Our Sun's average as stars go
Formed 5 billion years ago
Halfway through its life so far
Twinkle twinkle little star
Sunspots look dark but they're bright
Slightly cooler so less light

Temporary surface scar
I know exactly what you are

Swelling up before it's dead
Cooling off and growing red
Then its end is not so far
Twinkle twinkle giant star

Twinkle twinkle all you stars
I know exactly what you are
