What is 1,000?

What is nuclear fusion?

200

The layer of the sun where energy finally breaks free and emits heat, light, and charged particles?

What are fiery halos?

500

This is the main, overall reason why the Sun can create massive amounts of heat and pressure, while a planet made of the same gas (like Jupiter) can not. 

What is because the Sun is much bigger/has more mass/has more gravity?
