The sun is a natural object that emits light in the form of electromagnetic radiation, including visible light. Artificially, light bulbs and LED lights are examples of objects that produce light.
Luminescent. If is a biological process, it is called bioluminescence.
because there is no light for it to reflect off
The sun gives off light through a process called nuclear fusion in its core. This light then travels through space and reaches Earth, where some of it is reflected off surfaces like clouds, water, and sand.
The photosphere gives off heat and visible light.
No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)

A torch emits light from the bulb. A mirror gives off light by reflection.

If an object gives off light, it is a luminous object.The luminous object gives off its energy and we see it. If you shine light on an object, it is an illuminated object, it just reflects the light back into your eyes.
When light hits a green object, the object absorbs all the colors in the light spectrum except for green. Green is reflected off the object, which is why we perceive it as green. This reflection is what gives the object its color.
light relflects off of the object you are looking at and your retna gives it color as your brain flips the object right-side up
The sun. All other objects reflect heat and light from the sun.
Probably not a star. Could be a black hole, asteroid, or other spacial object.

It is a light source.
