What is the difference between the sun and a candle?

There are many differences:

1. The sun is held together by its own gravity, a candle is not.

2. On the sun, H atoms get converted into He atoms.

3. The sun will give heat and light for roughly 5 billion more years; we can extinguish a candle with a breath or with a touch.

4. The sun rotates about its own axis; candles do not.

5. Sunlight comes from nuclear reactions; candle light comes from simple combustion.

6. And the most idiotic difference is that a candle can provide direct heat and light at night but not the sun.

The BIG PICTURE:

They differ in size, durability, origin, the mechanism of energy output, and the quantity of energy output.
