The object that gives off its own light is a star.

Here's why:

* Stars produce their own light through nuclear fusion. This process happens within the core of the star, where immense pressure and heat fuse hydrogen atoms into helium, releasing enormous amounts of energy in the form of light and heat.

While other objects might appear to give off light, they are actually reflecting light from another source:

* The moon: Reflects sunlight.

* Planets: Reflect sunlight.

* Light bulbs: Convert electrical energy into light.
