* The Sun is a star: It's a giant ball of hot gas that produces its own light and heat through nuclear fusion.

* The Moon is a natural satellite: It orbits the Earth and reflects the sun's light.

Here's a table summarizing the differences:

| Feature | Sun | Moon |

|---|---|---|

| Type | Star | Natural Satellite |

| Light source | Produces its own light | Reflects the sun's light |

| Size | Much larger than Earth | Smaller than Earth |

| Composition | Mostly hydrogen and helium gas | Primarily rock and dust |

| Temperature | Extremely hot (millions of degrees Celsius) | Very cold (average -18°C) |

| Life | No life | No life |

So, while we see both the sun and moon in the sky, they are vastly different objects in space.
